Definitions
- the present invention relates to 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutanamide (hereinafter abbreviated as “compound (1)”), which is a selective muscular force receptor antagonist.
- compound (1) 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutanamide
- the present invention relates to a novel production intermediate and a method for producing a compound (1) using the intermediate. Background art
- Non-Patent Document 1 Bioorg. Med. Chem., 7 (6), 1151-1161 (1999) Disclosure of the Invention
- an industrially advantageous production method of 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutanamide has been established, and can be provided as a high-purity and high-quality pharmaceutical product. It is.
- 4- (2-Methyl-1-imidazolyl) -2,2-diphenylbutane amide salt is an inorganic acid addition salt with hydrochloric acid, sulfuric acid, hydrobromic acid or phosphoric acid, or maleic acid. It means an organic acid addition salt with acid, fumaric acid, acetic acid, oxalic acid, tartaric acid or benzenesulfonic acid. Of these, hydrochloride or phosphate is preferable.
- the present invention provides a crude crystal of 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutane amide according to Patent Document 3, which is methanol, ethanol, propanol, 2-propanol And then add an acid such as hydrochloric acid or phosphoric acid of this mole, then add an organic solvent such as ethyl acetate, or equimolar acid such as hydrochloric acid or phosphoric acid, alcohol, By crystallization using a mixed solution of ethyl acetate, acid salts such as hydrochloric acid or phosphate of 4- (2-methyl-1-imidazolyl) -2,2-diphenylbenzeneamide or the like And then neutralized with an alkaline metal hydroxide, and then reconstituted from alcohols such as methanol, ethanol, propanol, 2-propanol, or these hydrous alcohols. By crystallizing, it is easy to operate with simple operation. Effect well, and it found that the high purity of the
- the acidic salt of 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutanamide or phosphate of the present invention or a hydrate of these salts is a specific example. It was a new compound that was not disclosed, and its usefulness was not known. It has been found that the use of these novel salts or hydrates of the salts improves the purification efficiency and simplifies the purification operation, and the present invention has been completed as an industrial method.
- the crude product can be obtained as a high-quality compound (1) with a high yield only by simple recrystallization without using a synthetic adsorbent.
- the present invention provides an excellent industrial production method for the compound (1).
- the wet crystals were dissolved in 100 mL of 95% 2-propanol by heating, 100 mL of ethyl acetate was added, and the mixture was stirred and crystallized at room temperature for 1 hour, and then cooled with ice water. After stirring at an internal temperature of 15 ° C or lower for 1 hour, the crystals were collected by filtration and washed with 10 mL of ethyl acetate. Drying under reduced pressure (vacuum pump) at 60 ° C for 3 hours gave 16.9 g (79.3%) of 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutane amide hydrochloride.
- This hydrochloride was heated and completely dissolved in 80 mL of 90% 2-propanol, 160 mL of ethyl acetate was added, and the mixture was stirred and crystallized at room temperature for 1 hour, and then cooled with ice water. After stirring for 1 hour at an internal temperature of 15 ° C or lower, the crystals were collected by filtration and washed with 10 mL of ethyl acetate. Reduce the pressure by drying at 60 ° C for 3 hours (vacuum pump), and add 14.5 of white crystalline powder 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutaneamide hydrochloride to 14.5 g (total yield: 68%).
- UV absorptiometer (measurement wavelength: 227 nm)
- Mobile phase Dissolve 2.16 g of sodium 1-octanesulfonate in diluted phosphoric acid (1 1000). The resulting solution is 1000 mL mobile phase A, and acetonitrile is mobile phase B. Mobile node C is mobile phase C. For 40 minutes after sample injection, linear concentration gradient from mobile phase A / mobile phase B / mobile phase C mixture (12: 5: 3) to mobile phase B / mobile phase A / mobile phase C mixture (12: 5: 3) Liquid is transferred by control, and for the next 10 minutes, mobile phase B / mobile phase A / mobile phase C mixed liquid (12: 5: 3) is supplied.
- 4- (2-methyl-1-diimidazolyl) -2,2-diphenylbutane amide 4- (2-methyl-diimidazolyl) -2,2- Diphenylbutane amide is isolated as an acid salt such as hydrochloride or phosphate or its hydrate, purified, then recrystallized with alkali metal hydroxide and alcohol.
- an acid salt such as hydrochloride or phosphate or its hydrate
- an industrially advantageous production method of 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutanamide has been established and can be provided as a high-purity and high-quality pharmaceutical product. It has become possible.
