Participants

Reaction Steps

To methyl 4-({2-[[5-(4-t-butylphenyl)-4-hydroxy-1-methyl-1H-pyrazol-3-yl](phenyl)methylene]hydrazino}carbonyl)benzoate (0.196 mmol, 100 mg), methanol (4 mL) was added, and 1 M aqueous sodium hydroxide (0.981 mmol, 0.981 mL) was added at room temperature. After 15 minutes of stirring at room temperature and 1 hour of stirring at 60° C., the reactor was cooled to room temperature, and 1 M hydrochloric acid (0.981 mmol, 0.981 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 (93 mg, yield 95%).
