Description

PROCESSES FOR THE PREPARATION OF FUNGICIDAL COMPOUNDS
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit under 35 U.S.C. 119(e) to U.S.
Provisional Application Number 62/466,944, filed on March 3, 2017, the entirety of which is incorporated herein by reference.
FIELD
[0002] Provided herein are processes for the preparation of stereomerically enriched compounds that are useful as fungicides.
BACKGROUND
[0003] Acetyl-CoA carboxylase ("ACCase") is an essential catalyst for the rate-limiting step of fatty acid biosynthesis in both eukaryotes and prokaryotes.
Phytopathogenic fungi can infect crop plants either in the field or after harvesting, resulting in considerable economic losses to farmers and producers worldwide. In addition to the agricultural impact, when food and feed contaminated with fungi or the toxins they produce are ingested by humans or livestock, a number of debilitating diseases or death can occur. Approximately 10,000 species of fungi are known to damage crops and affect quality and yield. Crop rotation, breeding of resistant cultivars, the application of agrochemicals and combinations of these strategies is commonly employed to stem the spread of fungal pathogens and the diseases they cause.
[0004] Compounds that exhibit fungicidal activity, and which are useful in the preparation of compositions and in accordance with methods for control of fungal pathogens, are described in U.S. Patent Publication Nos. 2017/0166584, 2017/0166582, 2017/0166583, and 2017/0166585, each filed on November 22, 2016, the entirety of which are incorporated herein by reference.
[0005] There is a need in the art to provide processes and methods for the synthesis of these and other compounds exhibiting fungicidal activity.

[00154] 1-Fluoro-4-methoxybenzene (compound 1.1, 38 mL, 330 mmol, 1.2 eq.) (HPLC retention time=3.535) was added to a 500-mL 4-necked flask containing a mixture of methanesulfonic anhydride (48.6 g, 279 mmol, 1 eq.) and chloroacetic acid (32.0 g, 339 mmol, 1.2 eq.). The mixture was placed in an oil bath under nitrogen and heated to 80 C (bath temperature) with mechanical stirring and internal temperature monitoring. The maximum internal temperature was 75 C. HPLC analysis after 1.5 hours showed little conversion to ketone compound 1.2. HPLC after an additional hour showed 36% conversion to the desired product (retention time=3.650 min) when adjusted for differences in extinction coefficients between starting material and product. Water (49 mL) was added to the mixture dropwise via addition funnel (drop the oil bath, keeping internal temp below 95 C). The mixture was allowed to stir for 15 minutes during which time the internal temperature had dropped to 73 C. n-Propanol (100 mL) was added to the mixture and the temperature was increased to 80 C. As the reaction was allowed to cool, additional n-propanol was added to maintain a homogeneous solution (20 mL). The reaction was seeded at 50 C and allowed to further cool to room temperature overnight with continued slow stirring. Crystallization began at ¨40 C. The reaction was cooled to 0 C with an ice bath and allowed to stir an additional 1 hour then the solid was isolated by suction filtration. The solid was washed with cold 30%
water in n-propanol (3 x 50 mL, fully deliquored) and water (3 x 50 mL). The solid (-26 g wet) was placed on the nitrogen press (15 scfh) to dry. After 3 hours, the solid was weighed (22.2 g) and returned to the press for 2 hours. No change in mass was observed. Compound 1.2 (22.2 g; 39%) was isolated as a white crystalline solid. 33% yield based on anisole. lEINMR (300 MHz, CDC13) 8 ppm 7.59 (dd, J = 8.8, 3.3 Hz, 1H), 7.23 (m, 1H), 6.96 (dd, J = 9.1, 4.0 Hz, 1H), 4.78 (s, 2H), 3.95 (s, 3H).
[00155] Example 1.3: Preparation of N-Isopropyl-2-methyl-2-15-methyl-2,4-dioxo-6-(211-1,2,3-triazol-2-y1)-1,4-dihydrothieno[2,3-dlpyrimidin-3(211)-y1]propanamide (compound 2.2)
[00156] A 250-mL round bottomed flask was charged with acid 2.1 (15.4 g, 45.9 mmol, 1 eq.), HATU (19.2 g, 50.5 mmol, 1.1 eq.), and 2-MeTHF (50 mL, 500 mmol), in sequence, at room temperature. DIEA (20.0 mL, 115 mmol, 2.5 eq.) and isopropylamine (9.80 mL, 115 mmol, 2.5 eq.) were added sequentially in a dropwise manner and the resulting mixture was stirred under ambient conditions. When complete consumption of acid 2.1 was observed by HPLC, the reaction was quenched with 1M aqueous HC1 and transferred to a separatory funnel containing 1 M aqueous HC1 and ethyl acetate. The layers were separated and the aqueous phase was extracted with ethyl acetate (2x). The combined organic phases were washed with saturated aqueous sodium bicarbonate, brine, dried with magnesium sulfate, filtered, and concentrated.
The crude material was recrystallized from hot acetone to yield amide 2.2 as brown solid (2 crops, 13.7 g, 79%). 1-EINMR (400 MHz, DMSO-d6) 6 ppm 11.96 (s, 1 H), 8.14 (s, 2 H), 7.33 (d, J = 8.1 Hz, 1 H), 3.75-3.90 (m, 1 H), 2.47 (s, 3 H), 1.61 (s, 6H), 0.99 (s, 3 H), 0.97 (s, 3 H).
[00157] Example 1.4: Preparation of N-Isopropyl-2-methyl-2-15-methyl-2,4-dioxo-6-(211-1,2,3-triazol-2-y1)-1,4-dihydrothieno[2,3-dlpyrimidin-3(211)-y1]propanamide (compound 3.1)
[00158] A 250-mL round bottomed flask was charged with amide 2.2 (2.76 g, 7.33 mmol, 1.0 eq.), ketone 1.2 (1.78 g, 8.80 mmol, 1.2 eq.), potassium carbonate (2.53 g, 18.3 mmol, 2.5 eq.), sodium bromide (37.7 mg, 0.366 mmol, 5 mol%), and acetonitrile (24.0 mL, 8.7 vol), in sequence, at room temperature. The reaction mixture was heated to 50 C and the resulting solution was allowed to stir overnight under an ambient atmosphere.
After stirring overnight, the reaction did not reach full conversion as determined by HPLC
analysis.
Additional potassium carbonate (1.01 g, 7.33 mmol) was added and the reaction was continued.
Once the reaction mixture contained less than 5% amide 2.2 as judged by HPLC, the reaction was quenched by adding water and the product precipitated from the stirring solution. The heterogeneous solution was vigorously stirred for 1 hour and the precipitate was filtered, washed with water, and dried to give the crude product as a brown solid. The crude material was dissolved in THF (3 mL) and activated carbon (-25 mg) was added. The resulting mixture was stirred overnight under ambient conditions. The mixture was filtered over MAGNESOL, eluting with ethyl acetate. The filtrate was concentrated and the crude material was crystallized from hot hexanes/ethyl acetate to afford ketone 3.1 as a light brown solid (two crops, 2.6 g, 66%).

[00160] A 500-mL round bottom flask was charged with ketone 3.1 (17.1 g, 31.5 mmol, 1 eq.), RuC1RS,S)-TsdpenKmesitylene) (196 mg, 0.32 mmol, 1 mol%), sodium formate (10.7 g, 158 mmol, 5.0 eq.), water (15 mL, 0.9 vol), and isopropanol (15 mL, 0.9 vol), in sequence, under ambient conditions. The reaction mixture was heated to 75 C
and reaction progress was monitored by HPLC. After stirring -3 hours, HPLC analysis indicated complete consumption of ketone 3.1. The flask was cooled to room temperature, transferred to a 2-L
round bottom flask, diluted with water (-90 vol), and stirred overnight. The precipitated solid was filtered, washed with water, dried, and collected to afford the crude product. The resulting precipitate was purified by MPLC (Silica Gold (Isco, 120 g HP Silica), 5-40%
ethyl acetate in dichloromethane, 85 ml/min, 12.5 column vol.) to give alcohol 4.1 as a white foam (13.5 g, 76%, 92% ee). Further purification can done by crystallizing the material from hot tert-butyl methyl ether and hexanes. NMR (400 MHz, DMSO-d6) 8 ppm 8.16 (s, 2 H), 7.20-7.31 (m, 2 H), 7.05 (td, J = 8.5, 3.2 Hz, 1 H), 6.93 (dd, J = 9.1, 4.3 Hz, 1 H), 5.82 (d, J = 4.3 Hz, 1 H), 5.29-5.36 (m, 1 H), 3.94-4.06 (m, 1 H), 3.79-3.92 (m, 2 H), 3.71 (s, 3 H), 2.51 (s, 3 H), 1.63 (s, 3 H), 1.63 (s, 3 H), 1.01 (s, 3 H), 0.99 (s, 3 H).
[00161] Example 1.6: Preparation of 2-Methoxyethyl 2-{1-1(2R)-2-(5-fluoro-2-methoxypheny1)-2-hydroxyethyll-5-methyl-2,4-dioxo-6-(211-1,2,3-triazol-2-y1)-1,4-dihydrothieno[2,3-dlpyrimidin-3(211)-y11-2-methylpropanoate (compound 1-074)
[00162] Alcohol 4.1 was placed in an amber bottle and dried overnight in a vacuum oven set to 60 C. The vessel was removed from the vacuum oven, cooled to room temperature, and subsequently used in the following reaction. Later experiments identified that rigorous drying is not essential for reaction success. Lots used within these examples typically contained 0.5% water or less as determined by KF analysis.
[00163] A 20-mL scintillation vial was charged with alcohol 4.1 (218 mg, 0.400 mmol, 1 eq.) and 1,2-dimethoxyethane (650 L, 3.0 vol) under ambient conditions. It should be noted that increasing the reaction temperature at any point during the course of the reaction leads to greater loss of stereochemical integrity. Whereas decreasing the reaction temperature to 5 C

led to a marginal improvement in the stereochemical erosion (loss of chiral integrity to ¨10% ee) and decreasing the reaction temperature to -40 C led to no observable reaction.
[00164] 2,6-Lutidine (139 tL, 1.20 mmol, 3.0 eq.) and methanesulfonic anhydride (115 mg, 660 i.tmol, 1.65 eq.) were added sequentially, each as single charges, under ambient conditions and the reaction was sealed with a screw-top cap that was fitted with a Teflon-lined septum. The resulting reaction mixture was aged 2 hours (at least one hour for this activation period is required for full conversion) at which time 2-methoxyethanol (950 tL, 12.0 mmol, 30 eq.) was added in one portion and the resulting solution was stirred under ambient conditions.
After 24 hours, the reaction reached complete starting material consumption as determined by HPLC and MS. The resulting reaction mixture was quenched with 1M aqueous HC1 (3 mL, 14 vol) and further diluted with water (-10 mL, 60 vol) which caused the product to precipitate from the solution. The solid was filtered, washed with water, and dried to afford compound I-074 as a white solid (223 mg, 91%, 79% ee).

[00185] A stirred heterogeneous mixture of diethyl 5-amino-3-methylthiophene-2,4-dicarboxylate (compound 2, 9.00 g, 35.0 mmol) in dry acetonitrile (45 mL) under nitrogen was treated with CDI (7.09 g, 43.7 mmol) followed by triethylamine (24.4 mL, 175 mmol). The mixture was heated to 50 C. The resulting homogenous mixture was stirred at 50 C for 4 hours, at which point HPLC indicated complete conversion to the acyl imidazole intermediate.
HPLC was performed on aliquots of the mixture quenched with morpholine. tert-Butyl 2-methylalaninate hydrochloride (8.56 g, 43.7 mmol) was added to form a slightly heterogeneous mixture. The mixture was stirred at 50 C for 1.5 hours. Stirring was continued overnight at room temperature. The mixture was diluted with water (100 mL), and the resulting solids were filtered, washed with water (6 x 30 mL), and dried in a vacuum oven at 40 C
over the weekend to give compound 3 (15.55 g, 100%) as a white solid. HPLC indicated a purity of greater than 99% (5.44 min retention time). 1-EINNIR (300 MHz, DMSO-d6) 6 ppm 10.60 (s, 1H), 8.41 (s, 1H), 4.33 (q, J = 6.9 Hz, 2H), 4.22 (q, J = 6.9 Hz, 2H), 2.66 (s, 3H), 1.37 (s, 9H), 1.38-1.24 (m, 12H).

[00187] A stirred heterogeneous mixture of compound 3(12.00 g, 27.12 mmol) in dry acetonitrile (120 mL) under nitrogen was treated with potassium tert-butoxide (6.08 g, 54.2 mmol). The tan, nearly homogeneous mixture was stirred at room temperature.
Within minutes, the mixture became cloudy. HPLC after a reaction time of 12 minutes showed -2%
of compound 3 remaining, with 80% of compound 4 and -8% acid by-product resulting from ethyl ester hydrolysis of compound 4. After 20 minutes of reacting, the reaction was quenched quickly with 0.05 M aqueous citric acid (-550 mL, -27 mmol). The mixture cleared during this addition, and the product precipitated out to give a thick slurry. The mixture was stirred for 8-10 minutes, and the solids were filtered, washed with water (5 x 120 mL) and dried in a vacuum oven at 45 C over the weekend to give compound 4 (8.75 g, 77%) as a white solid.

[00189] A thick, stirring slurry of compound 4 (2.00 g, 5.04 mmol) in dry acetonitrile (36 mL) under nitrogen was treated sequentially with 2-chloro-1-(5-fluoro-2-methoxyphenyl)ethanone (compound 1, 1.23 g, 6.05 mmol), NaBr (52 mg, 0.50 mmol) and K2CO3 (1.74 g, 12.6 mmol) while being warmed to 60 C. During heating, it was necessary to keep the reaction stirred. The resulting pale yellow, heterogeneous mixture was stirred at 60 C
overnight and monitored by HPLC for consumption of compound 4. At 24 hours, the mixture was cooled to room temperature, diluted with water (40 mL) and extracted with Et0Ac (50 mL
+ 25 mL). The combined organic phase was washed with water (25 mL) and brine (15 mL), dried over MgSO4, and concentrated and dried under vacuum to give the crude product. The crude product was then triturated with Et0H (12 mL) with sonication and filtered. The solids were washed with Et0H (4 x 3 mL) and dried in a vacuum oven at 40 C over the weekend to give compound 5 (2.51 g, 88%) as a faint yellow solid. HPLC indicated a purity of 98.5% (5.87 min r.t.). 1H NMR (300 MHz, DMSO-d6) 6 ppm 7.58 (m, 1H), 7.50 (dd, J = 9.0, 3.3 Hz, 1H), 7.35 (dd, J = 9,0, 3.9 Hz, 1H), 5.35 (s, 2H), 4.25 (q, J = 7.2 Hz, 2H), 3.99 (s, 3H), 2.75 (s, 3H), 1.63 (s, 6H), 1.35 (s, 9H), 1.26 (t, J = 7.2 Hz, 3H).

[00191] A thick, stirred slurry of compound 5 (5.40 g, 9.60 mmol) in isopropyl alcohol/water (1:1, 22 mL) under nitrogen was warmed to 50 C and treated with sodium formate (3.26 g, 48.0 mmol) and RuCl[(S,S)-Tsdpen](mesitylene) (60.0 mg, 0.0964 mmol). The resulting mixture was heated to 75 C, at which point most solids had dissolved. The mixture was stirred vigorously for 2 hours, at which point HPLC indicated complete reaction. The mixture was cooled to room temperature, added portion-wise to water (-150 mL), and stirred for 15 minutes. The resulting solids (some tacky material also formed) were isolated by filtration, rinsing in and washing with -5% acetonitrile/water (2 x 50 mL). The filtration became sluggish, and a significant amount of tacky residue settled out. Because of the tacky residue, it may be necessary to do an aqueous workup and then flush through a pad of MAGNESOL.
The solids were dried in the vacuum oven at 40 C overnight to give compound 6 (5.24 g, 97%) as a light brown foam. A portion of this solid (2.41 g) was taken up in a minimum of dichloromethane and flushed through a pad of MAGNESOL (7.5 g) using dichloromethane (-75 mL) as eluent.
The filtrate was concentrated and dried under high vacuum to give a quantitative recovery of the product as a beige foam (dark impurities removed). HPLC indicated a purity of 98.9% (5.59 min retention time). Chiral HPLC, 96.3% ee.

[00193] A stirred mixture of compound 6 (2.77 g, 4.90 mmol) in acetonitrile (28 mL) under nitrogen was cooled to 0-5 C and treated with acrylonitrile (1.61 mL, 24.5 mmol) followed by 40% aqueous KOH (150 tL, 1.5 mmol). The resulting mixture was stirred at 0-5 C and monitored by HPLC for consumption of compound 6. At 3 hours, the mixture was diluted dropwise with water (80 mL) and extracted with Et0Ac (80 mL). The organic phase was washed with water (50 mL) and brine (25 mL), dried over MgSO4, and concentrated and dried under vacuum. The crude product [3.01 g light brown foam at 93.8% HPLC purity, 93% yield]
was combined with a similar batch of product and purified by silica gel chromatography (40 g cartridge, 10-30% Et0Ac/hexanes eluent) to give 86% (avg. combined yield) of compound 7 as a white foam. Silica gel chromatography was used to afford an upgrade in purity at this step since initial attempts to triturate or crystallize had failed in the chiral series. HPLC indicated a purity of 96.4% (5.67 min retention time). Chiral HPLC, 96.8% ee. 1H NMR (300 MHz, DMSO-d6) 6 ppm 7.20 (dd, J = 9.3, 3.0 Hz, 1H), 7.14 (m, 1H), 7.00 (dd, J =

[00196] Example 3.7a: Preparation of compound 8 using formic acid
[00197] A stirred mixture of compound 7 (4.87 g, 7.88 mmol) in Et0H (24 mL) under nitrogen was treated with formic acid (24 mL), and the mixture was heated to gentle reflux (78-80 C) and monitored by HPLC for consumption of compound 7. At 48 hours, the mixture was cooled to room temperature and stirred overnight to allow the product to precipitate out. The resulting solids were isolated by filtration, rinsing in with water (3 x 15 mL) and washing with water (4 x 20 mL), and dried in the vacuum oven at 45 C
overnight to give compound 8(3.33 g, 75%) as a white solid. HPLC indicated a purity of 98.1%
(4.49 min retention time). The filtrate was extracted with Et0Ac (50 mL), and the organic phase was washed with water (25 mL) and brine (20 mL), dried over MgSO4 and concentrated and dried under vacuum to give additional crude product (77% HPLC purity). These solids were slurried in isopropyl alcohol (9.5 mL, 10 V) for 1 hour, filtered, washed with isopropyl alcohol (4 x 1 mL), and dried in a vacuum oven at 45 C overnight to give additional compound 8 (655 mg, 14%) as a white solid. HPLC, 93.2% purity (4.48 min retention time).
[00198] Example 3.7b: Preparation of compound 8 using sulfuric acid
[00199] A stirred mixture of compound 7 (199 mg, 0.322 mmol) in isopropyl alcohol (1 mL) in a small vial was treated with 9 M sulfuric acid (1 mL) dropwise. The resulting thick, white slurry was stirred at room temperature and monitored for consumption of compound 7.
Additional isopropyl alcohol (0.5 mL) and concentrated H2SO4 (2-3 drops) were added to thin out the slurry and push the reaction to completion. At 44 hours, the reaction mixture was added dropwise to water (8 mL), rinsing in with additional water (4 mL), and the slurry was stirred for several minutes. The solids were isolated by filtration, washed with water (4 x 3 mL) and dried in a vacuum oven at 45 C overnight to give compound 8 (165 mg, 91%) as a white solid.

[00201] Compound 1-181 was prepared with methods using acid chloride (Example 3.8a) and propylphosphonic anhydride (Example 3.8b).
[00202] Example 3.8a: Preparation of Compound 1-181 using acid chloride
[00203] A flame-dried flask was charged compound 8 (225 mg, 0.401 mmol) and dry dichloromethane (2.2 mL) under nitrogen, and the stirred white slurry was treated with oxalyl chloride (35.6 L, 0.421 mmol) dropwise followed by catalytic DMF (6.2 L, 0.080 mmol).
Gas evolution occurred, the mixture thinned initially, and then a white precipitate began forming. The resulting slurry was stirred vigorously at room temperature for 2 hours, at which point HPLC (aliquot quenched into Me0H to form the methyl ester) indicated <5%
compound 8 remaining. The mixture was treated with isopropylamine (171 L, 2.00 mmol) quickly via syringe below the solvent line to give a homogeneous mixture. The flask was sealed, and the mixture was allowed to stir at room temperature overnight, although HPLC

The reaction was diluted with dichloromethane (20 mL), washed with water (2 x 15 mL) and brine (10 mL), dried over Na2SO4, and concentrated and dried under vacuum. The crude product was purified by silica gel chromatography (40 g cartridge, 35-55% Et0Ac/hexanes eluent) and the product fractions were pooled, concentrated and stripped down from Me0H several times to give compound 1-181 (226 mg, 94%) as a white solid. HPLC indicated a purity of 99.7% (4.76 min retention time). Chiral HPLC, >99% ee.
[00204] Example 3.8b: Preparation of Compound 1-181 using propylphosphonic anhydride
[00205] A stirred slurry of compound 8 (100 mg, 0.178 mmol) in dry dichloromethane (1.0 mL) under nitrogen was treated with triethylamine (74.4 L, 0.534 mmol) dropwise. Once the mixture had cleared, isopropylamine (75.8 L, 0.890 mmol) and propylphosphonic anhydride (50% in Et0Ac, 159 L, 0.267 mmol) were added dropwise (created a slight exotherm), and the resulting mixture was stirred at room temperature. HPLC
indicated ¨88% conversion at 15 minutes, but little change overnight. At 18 hours, additional isopropylamine (15 L, 1 eq.) and propylphosphonic anhydride (53 L, 0.5 eq.) were added, and the mixture was stirred for 1.5 hours, diluted with dichloromethane (15 mL), washed with water (2 x 10 mL) and brine (5 mL), dried over Na2SO4, and concentrated and dried under vacuum.
Purification by radial chromatography (2000 micron silica gel rotor, 60%
Et0Ac/hexanes eluent) gave compound 1-181 (108 mg, 100%) as a white film. HPLC indicated a purity of 99.7% (4.75 min retention time). Chiral HPLC, >99% ee.
