Reaction Steps

To methyl 4-{[2-(1-{4-hydroxy-1-methyl-5-[3-(trifluoromethyl)phenyl]-1H-pyrazol-3-yl}ethylidene)hydrazino]carbonyl}benzoate (0.072 mmol, 33.1 mg), methanol (2 mL) was added, and 1 M aqueous sodium hydroxide (5 eq., 0.360 mL) was added at room temperature. After 30 minutes of stirring at room temperature and 1.5 hours of stirring at 60° C., the reactor was cooled to 0° C., and 1 M hydrochloric acid (5 eq., 0.360 mL) and water were added. The precipitated solid was recovered by filtration, washed with water and dried by means of a vacuum pump to give the desired product as a yellow solid (17.6 mg, yield 55%).
