80% | With water; sodium hydroxide In methanol at 20℃; for 5 h; | To a solution of methyl 3-methoxy-1-methyl-1H-pyrazole-5-carboxylate (220.7 mg, 1.30 mmol) obtained in Example 235-B) in methanol (5 mL) was added 1M aqueous sodium hydroxide solution, and the mixture was stirred at room temperature for 5 hr. The reaction mixture was concentrated under reduced pressure, acidified with 1M hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate to give the title compound (163 mg) as a white solid (yield 80percent). MS (ESI-): [M-H]-155. 1H NMR (300 MHz, DMSO-d6) δ 3.77 (3H, s), 3.92 (3H, s), 6.20 (1H, s), 13.38 (1H, brs). |
40% | With hydrogenchloride; sodium hydroxide In methanol; di-isopropyl ether; water | Reference Example 58 Production of 3-methoxy-1-methyl-1H-pyrazole-5-carboxylic acid To a solution of methyl 3-methoxy-1-methyl-1H-pyrazole-5-carboxylate (2.01 g, 11.8 mmol) in methanol (15 mL) was added 8N aqueous sodium hydroxide solution (3.00 mL), and the mixture was stirred at room temperature for 18 hr. 6N Hydrochloric acid (4.00 mL) was added to the mixture, and the mixture was concentrated under reduced pressure. Water was added to the residue, and the precipitate was collected by filtration, washed with water and air-dried. The precipitate was suspended in diisopropyl ether, and the mixture was stirred at 80° C. for 15 min. After allowing to cool to room temperature, the precipitate was collected by filtration, washed with diisopropyl ether, and dried under reduced pressure to give the title compound (746 mg, yield 40percent) as a white solid. 1H-NMR (DMSO-d6, 300 MHz) δ 3.77 (3H, s), 3.93 (3H, s), 6.20 (1H, s), 13.37 (1H, br s). |
