2-difluoromethylthio-N-[(5,6-dihydro-4-methylfuro[2,3-d]pyrimidin-2-yl)aminocarbonyl]benzenesulfonamide, m.p. 184°-189° C.
The compounds of Formula I can be prepared by methods described or referred to in U.S. Pat. Nos. 4,169,719; 4,127,405; 4,339,267 and 4,394,506.
Compounds of Formula I can also be prepared by one or more of the methods shown in Equations 1-7.
As shown in Equation 1, compounds of Formula I can be prepared by treating sulfonamides of Formula II with phenyl esters of N-heterocyclic carbamic acids of Formula III in the presence of a strong organic base such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). ##STR12## wherein R, R1, R2 and A are as previously defined.
The reaction of Equation 1 is generally carried out in the range of 20° to 50° C. in an inert solvent such as dioxane or acetonitrile, analogous to methods taught in EP-A No. 44,807. The required carbamates can be prepared from the corresponding amines, IIIa, and diphenyl carbonate or phenylchloroformate and a base such as sodium hydride as shown in Equation 2. ##STR13##
Compounds of Formula I may also be prepared as shown in Equation 3 by treating sulfonamides of Formula II with the methyl ester of an N-heterocyclic carbamic acid of Formula IIIb in presence of an equimolar quantity of trimethylaluminum. ##STR14##
The reaction of Equation 3 is best carried out at temperatures between 25° and 83° C. in a solvent such as methylene chloride or 1,2-dichloroethane for 12 to 95 hours under an inert atmosphere, as taught in EP-A No. 84,244. The methyl carbamates, IIIb, can be conveniently synthesized by treatment of the corresponding heterocyclic amines of Formula IIIa with dimethyl carbonate or methyl chloroformate in the presence of a base such as sodium hydride.
Alternatively, compounds of Formula I can be prepared by the reaction of a sulfonylcarbamate of Formula IV with an aminoheterocycle of Formula IIIa as shown in Equation 4. ##STR15##
The reaction is carried out at 50° to 100° C. in a solvent such as dioxane for 0.5 to 24 hours as taught in EP-A No. 44,807. The required carbamates of Formula IV are prepared by the reaction of the corresponding sulfonamides of Formula II with diphenylcarbonate or phenylchloroformate in the presence of a base such as sodium hydride.
Sulfonamides of Formula II used in the preparation of compounds of Formula I are useful intermediates. They can be prepared by a variety of methods known in the art. For example, contacting an appropriately substituted sulfonyl chloride IIa with ammonium hydroxide or ammonia in an inert solvent such as ether or tetrahydrofuran affords sulfonamides II as shown by Equation 5a and 5b. ##STR16##
The reaction of sulfonyl chloride, IIa, with ammonia is best carried out at -33° to 50° C. for 0.1 to 24 hours. After removal of the ammonium chloride by-product by filtration or extraction with water, the desired product can be isolated by the evaporation of the organic solvent.
Ammonium hydroxide can be used in place of ammonia as in Equation 5b. This reaction is widely reported in the literature, c.f., Methoden Der Organischen Chemie (Houben-Weyl), vol. 9, Ch. 19, edited by F. Muth, Stuttgart, 1955.
Alternatively, sulfonamides of Formula II can be prepared by the reaction of a lithium salt of an appropriately substituted sulfinic acid, IIb, with chloramine as shown in Equation 6. ##STR17##
This reaction can be carried out using the conditions referred to in the preceding reference.
Lithium salts of Formula IIb can also be converted to the sulfonamides of Formula IIa by the procedures taught in U.S. Pat. No. 4,441,910.
Sulfonyl chlorides of Formula IIa can be prepared by the reaction of lithium salts of Formula IIc with sulfuryl chloride at -50° to -20° C. in an inert solvent such as tetrahydrofuran or ether as shown in Equation 7. ##STR18##
In Equation 7, R' is a group such as butyl, phenyl, diisopropylamido or similar moiety commonly employed as lithiation agents. These agents and their method of use are described in N. S. Narasimhan and R. S. Mali, Synthesis, 957-86 (1983) or in The Chemistry of Organolithium Compounds, Wakefield, Pergamon Press, Oxford, 1974 or also H. W. Gschwend and H. R. Rodriguez, Org. React. 26, 1 (1978).
The sulfonyl chlorides, IIa, can be isolated by extracting the inorganic by-products with water followed by drying the organic layer over a drying agent such as magnesium sulfate, filtering the dried solution and evaporation of the solvent.
Lithium salts of formula IIb can be prepared by contacting sulfur dioxide with the lithiated intermediate IIc using procedures described in the above references.
Sulfonamides of Formula II can be synthesized by methods described in U.S. Pat. No. 4,452,628 where R1 is haloalkoxy; U.S. Pat. No. 4,368,069 and South African Patent Application No. 83/6449 where R1 is substituted alkenyl. (EP-A) No. 102,924 described methods of synthesis for sulfonamides where R1 is azido; South African Patent Application No. 83/3779 discloses methods for the synthesis of sulfonamides where R1 is alkynyl and (EP-A) No. 112,803 describes the synthesis of sulfonamides of Formula II where R1 is dialkoxyphosphonyloxy.
The synthesis of heterocyclic amine derivatives such as those depicted by Formula IIIa where A is A-1, A-2 or A-3 is described in the following references:

Agriculturally suitable salts of compounds of Formula I are also useful herbicides and can be prepared in a number of ways known in the art. For example, metal salts can be made by contacting compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide or carbonate). Quaternary amine salts can be made by similar techniques.
Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contact of an aqueous solution of a salt of a compound of Formula I (e.g., alkali or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water and can be separated by filtration.
Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble.
Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like.
The preparation of the compounds of this invention is further illustrated by the following specific examples. Unless otherwise indicated, temperatures are given in degrees centigrade.
To 139.11 g of 2-nitrophenol in 500 ml of dimethylformamide was added 276.42 g of anhydrous potassium carbonate. The mixture was warmed ot 60° to form a red suspension and 100 ml of 1,1,2-trichloroethene was added dropwise. After stirring at 85° for 16 hours the mixture was cooled to room temperature, stirred for 4 hours at room temperature and then poured into 3 l of ice and water. The aqueous mixture was extracted five times with 500 ml portions of methylene chloride and the methylene chloride extracts were then washed with three portions of 500 ml 10% hydrochloric acid followed by three washes with 600 ml of water and one wash with 600 ml of saturated aqueous sodium chloride. After drying the organic phase over magnesium sulfate and evaporation of the solvent, 218.5 g of a yellow solid was obtained.
NMR (CDCl3): 7.99 (d, 1H, Armo.); 7.63 (t, 1H, Arom.); 7.31 (m, 2H, Arom.); and 6.08 (s, 1H, ═CClH).
Two hundred and eighteen grams of 1,2-dichloro-1-(2-nitrophenoxy)ethene in ethyl acetate with 2.2 g of 10% palladium-on-charcoal was treated with 60 pounds per square inch gauge of hydrogen at 60° until there was no further uptake of hydrogen. The reaction mixture was filtered through Celite® and concentrated in vacuo to yield a brown oil. This oil was taken up in 20% ethyl acetate/hexane and passed through a column of Florisil® two times to yield 169.5 g of oil after evaporation of the solvent.
NMR (CDCl3): 6.95 (d, 2H, Arom.); 6.8 (d, 2H, Arom.); 5.85 (s, 1H, ═CHCl); and 3.75 (broad s, 2H, NH2).
Twenty four grams of 1-(2-aminophenoxy)-1,2-dichloroethene was dissolved in a mixture of 25 ml acetic acid, 25 ml of 12N hydrochloric acid and 50 ml of water. The grown mixture was cooled to 0° and a solution of 8.28 g of sodium nitrite in 15 ml of water was added dropwise. The resulting brown suspension was stirred at below 5° for one-half hour and then added to a stirred suspension of 3 g copper sulfate, 90 ml of 12N hydrochloric acid and 62 ml of 40% sodium bisulfite. The resultant mixture was allowed to warm to room temperature and stirred for sixteen hours. It was then extracted with methylene chloride, the combined organic phases washed with water and saturated aqueous sodium chloride, dried over magnesium sulfate and added dropwise to 100 ml of methylene chloride containing 12.5 ml of liquified ammonia at -78°. This mixture was allowed to stir for two days at room temperature, then cooled to 0° and acidified with 10% hydrochloric acid. After separating the resultant two phases, the methylene chloride phase was washed with water and saturated sodium chloride followed by drying over magnesium sulfate and evaporation of the solvent to give 18.79 g of a solid melting at 145°-148°.
NMR (CDCl3): 8.00 (d, 1H, Arom.); 7.60 (t, 1H, Arom.); 7.30 (t, 1H, Arom.); 7.10 (d, 1H, Arom.); 6.15 (s, 1H, ═CClH); and 5.10 (bs, 2H, NH2).
2-(1,2-Dichloroethen-1-yloxy)benzenesulfonamide (13.4 g), 12.4 g of n-butyl isocyanate and 15.2 g of anhydrous potassium carbonate were combined in 200 ml of dry tetrahydrofuran and heated to reflux for three hours. The mixture was then cooled to room temperature, filtered and the solvent removed by evaporation. The residue and precipitate were recombined and dissolved in 600 ml of water and the mixture acidified with 10% hydrochloric acid. The resultant precipitate was removed by filtration, washed with water, air dried and then washed with hexane. After drying in vacuo at 80° overnight, 13.65 g of solid product melting at 122°-125° was obtained.
NMR (CDCl3): 8.01 (d, 1H, Arom.); 7.65 (t, 1H, Arom.); 7.31 (t, 1H, Arom.); 7.12 (d, 1H, Arom.); 6.48 (broad s, 1H, NH); 6.14 (s, 1H, CH); 3.21 (q, 2H, Ch2); 1.41 (m, 2H, Ch2); 1.27 (m, 2H, Ch2); and 0.87 (t, 3H, Ch3).
N-(n-Butylaminocarbonyl)-2-(1,2-dichloroethen-1-yloxy)benzenesulfonamide (11.03 g), 2.97 g of n-butyl isocyanate and 0.3 g of 1,4-diazabicyclo[2.2.2]octane (DABCO®) in xylene was heated to 135° and 2.2 ml of liquified phosgene was added portionwise while maintaining the temperature at 135°. The mixture was heated for 1.5 hours after all of the phosgene had been added, filtered and the xylene removed in vacuo to yield 10.8 g of an amber oil. The peak at 2220 cm-1 by infrared absorption spectroscopy confirmed the presence of the isocyanate function. This oil was diluted to 120 ml in methylene chloride.
To 300 mg of 2-amino-5,6-dihydro-4-methylfuro[2,3-d]pyrimidine in 25 ml of methylene chloride was added 20 ml of 2-(1,2-dichloroethen-1-yloxy)benzenesulfonyl isocyanate in methylene chloride from the previous example. After heating to reflux, the mixture was stirred overnight at room temfperature. Removal of the solvent in vacuo yielded an amber oil. Trituration of this oil with 1-chlorobutane gave a tan solid. After filtration and washing with ethyl ether, a yield of 0.8 g of a tan solid melting at 208°-210° was obtained.
NMR (CDCl3): 13.72 (broad s, 1H, NH); 9.18 (broad s, 1H, NH); 8.16 (d, 1H, Arom.); 7.63 (t, 1H, Arom.); 7.33 (t, 1H, Arom.); 7.07 (d, 1H, Arom.); 6.05 (s, 1H, CH); 4.73 (t, 2H, CH2); 3.21 (t, 2H, CH2); and 2.41 (t, 3H, CH3).
An infrared absorption peak at 1690 cm-1 was consistent for the desired urea carbonyl.
A mixture of 11.2 g of 2-difluoromethoxy-6-methylbenzenesulfonamide, 3 g of n-butyl isocyanate and several crystals (ca. 0.1 g) of DABCO® in 50 ml of mixed xylenes was heated under a dry ice reflux condenser to 135°. Phosgene was then passed into the flask until the temperature dropped to 120° whereupon the phosgene addition was halted. The addition was resumed when the temperature rose to 130° and once again halted when the reflux temperature had fallen to 120°. When the reflux remained at 120° without further addition of phosgene, the reaction was considered complete. The mixture was allowed to stand overnight at room temperature, filtered and the xylene distilled in vacuo. The solidified residue was triturated with 50 ml of 1-chlorobutane, filtered and the 1-chlorobutane distilled in vacuo to yield 8.3 g of the sulfonyl isocyanate whch showed a peak at 2240 cm-1 by infrared absorption spectroscopy. This material resolidified.
A mixture of 25 ml of methylene chloride, 0.8 g of 2-amino-5,6-dihydro-4-methylfuro[2,3-d]pyrimidine, a small crystal of DABCO® (Ca<0.1 g) and 1.5 g of 2-difluoromethoxy-6-methylbenzenesulfonyl isocylanate was heated to reflux for one hour, cooled and filtered to yield 1.7 g of solid, m.p. 213°-215°. It showed peaks at 1690 and 1640 cm-1 by infrared absorption spectroscopy, consistent for the desired product.

__________________________________________________________________________
Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:
______________________________________

High Strength 90-99 0-10 0-2
Compositions
______________________________________
*Active ingredient plus at least one of a Surfactant or a Diluent equals
100 weight percent.
Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.
Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers". 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, N.Y., 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., N.Y., 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.
The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

Test results indicate that the compounds of the present invention are highly active preemergent of postemergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Some of the compounds may have utility for selective weed control in crops such as wheat. Alternatively, the subject compounds are useful to modify plant growth.
The rates of application for the compounds of the invention are determined by a number of factors, including their use as plant growth modifiers or as herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.05 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for plant growth modification or for situations where only short-term persistence is required.
The compounds of the invention may be used in combination with any other commercial herbicide, examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types. The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow.
Seeds of crabgrass (Digitaria spp.). barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), cheatgrass (Bromus secalinus), sicklepod (Cassia obtusifolia), velvetleaf (Abutilon theophrasti), morningglory (Ipomoea spp.). cocklebur (Xanthium pensylvanicum), sorghum, corn, soybean, sugar beet, cotton, rice, wheat and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with the test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were compared to controls and visually rated for response to treatment. The ratings, summarized in Table A, are based on a numerical scale extending from 0=no injury, to 10=complete kill. A dash (--) response means no test. The accompanying descriptive symbols have the following meanings:
B=burn;
C=chlorosis or necrosis;
D=defoliation;
E=emergence inhibition;
G=growth retardation;
H=formative effects;
S=albinism;
U=unusual pigmentation;
X=axillary stimulation; and
6Y=abscised buds or flowers.
