Definitions
- the present invention relates to a method for producing olopatadine useful as a pharmaceutical product.
- Olopatadine (Z) -1 1 1 (3-dimethylaminopropylidene) 1,6,1 1-dihydrodivenes [b, e] oxepin 1 2-acetic acid) has the formula [I I]:
- the present invention provides a method for efficiently and industrially advantageously producing olopatadine useful as a pharmaceutical product.
- the Z compound represented by the following [I I] can be efficiently obtained by heating the ester compound represented by the following formula [I] in a solvent in the presence of an acid.
- Compound [I] can be produced by reacting compound [I I I] with compound [IV].
- the solvent used in the reaction examples include ethers (for example, tetrahydrofuran, diethyl ether, diisopropyl ether), aromatic hydrocarbons (for example, toluene, xylene) and the like, and mixed solvents thereof.
- the reaction temperature is usually 0 to 50. ° C.
- the compound [IV] (ie 3-dimethylaminopropyl magnesium halide) used here is prepared from, for example, 3-dimethylaminopropyl halide (3-dimethylaminopropyl chloride or bromide) and magnesium. You can.
- Compound [IV] is generally used in a proportion of 1 to 2 mol, preferably 1.1 to 1.7 mol, per 1 mol of compound [III].
- Compound [IV] is prepared by dissolving Compound [III] as a solution in a suitable solvent (for example, ⁇ trahydrofuran or toluene ⁇ trahydrofuran mixed solvent) at a concentration of about 10 to 4 ⁇ / ⁇ .
- a suitable solvent for example, ⁇ trahydrofuran or toluene ⁇ trahydrofuran mixed solvent
- the liquid temperature at the time of dropping is usually 0 to 50 ° C, preferably 10 to 30 ° C.
- the dropping time is usually 1 to 10 hours, preferably 1 to 3 hours.
- stirring for about 0.5 to 5 hours in order to allow the reaction to proceed sufficiently.
- compound [I] is isolated by performing conventional post-treatment methods such as extraction, liquid separation, washing, drying (dehydration), and concentration. can do.
- Compound [I I] can be produced by heating compound [I] in a solvent in the presence of an acid.
- Examples of the acid include hydrogen chloride and sulfuric acid, but hydrogen chloride is preferable. Hydrogen chloride may be used as a gas or hydrochloric acid. The amount of acid used is preferably about 1 to 5 mol per 1 mol of compound [I]. '
- an organic solvent or a mixture of an organic solvent and water is preferable.
- the mixing ratio of the organic solvent and water is usually 10 : 1 to 10: 3 by volume ratio.
- the organic solvent include esters (ethyl acetate, propyl acetate, butyl acetate, ethyl propionate, Propyl propionate, butyl propionate, etc.), ether (Jetyl ether, tert-butyl methyl ether, diethylene glycol dimethyl ether, diethylene glycol dibutyl ether, diethylene glycol monoethyl ether, 1,2-dimethoxyethane, tetrahydrofuran, etc.) Amides (N, N-dimethylformamide, N, N-dimethylacetamide, N-methysolepyrrolidone, 1,3-dimethyl-2-imidazolidinone, etc.), ketones (for example, methylisoptyl ketone, methyl ester) Tilket
- the heating temperature is usually from 50 ° C to 150 ° C, preferably from 80 ° C to 110 ° C.
- the reaction time is usually 0.5 to 20 hours, preferably 2 to 10 hours, although it depends on the temperature and the amount of raw materials used. This reaction is preferably carried out with stirring. Thus, dehydration reaction and deesterification reaction of compound [I] and isomerization of the resulting compound from E form to Z form proceed.
- the reaction is preferably carried out in a photoclave.
- hydrochloric acid or sulfuric acid is used as the acid, it is preferable to continuously distill off water azeotropically for the purpose of promoting the catabolization reaction after heating.
- the azeotropic distillation of water can be performed using a known distillation method, for example, using a Dean-Stark apparatus.
- the reaction solution in which water is distilled off azeotropically there is a Z-form rich compound [II].
- an acid addition salt corresponding to the acid used is obtained.
- Compound [II] can be obtained. It can also be purified by recrystallization from an appropriate solvent (for example, a mixed solvent of acetone and water).
- the acid addition salt of compound [II] can be subjected to alkali treatment according to a conventional method to lead to acid-free compound [II].
- Compound [III] which is a raw material compound of the present invention, is prepared according to the method described in Med. Chem., 19, 941 (1976), 20, 1499 (1977), or Japanese Patent Laid-Open No. 58-21679. (1 1 1 oxo 6, 1 1-dihydrodivenes [b, e] oxepin -2-yl) with acetic acid
- the present invention will be described below with reference to examples, but the present invention is not limited to these examples.
- the ratio of the E-form and the Z-form of the produced compound was determined from the value measured by high performance liquid chromatography (H P L C).
- H P L C high performance liquid chromatography
- % other than the area percentage of purity measured by HPLC represents “wt%”.
- T-Butanol 100m I was added thereto, and the mixture was stirred at about 20 ° C for 2 hours, and further stirred at 80 ° C for 2 hours. This was cooled to about 20 ° C., 600 ml of water was added, and the mixture was stirred for 20 minutes, followed by liquid separation.
- the organic layer was washed with 400 ml of water and then with a solution of 6.2 g (0.045 mol) of potassium carbonate in 10 ml of water.
- O g was added to the washed organic layer and stirred, followed by filtration through a Buchner low bottle to separate the activated carbon, and the activated carbon was washed with 50 ml of toluene on the top of the Buchner mouth.
- olopatadine useful as a medicine can be produced efficiently and industrially advantageously.
