Procedure

To a suspension of methyl 5-[(2-{1-[5-(4-trifluoromethylphenyl)-4-hydroxy-3-thienyl]ethylidene}hydrazino)carbonyl]-2-thiophenecarboxylate (56.2 mg, 0.12 mmol) in t-butanol (1.2 mL), 0.2 M sodium hydroxide aqueous solution (1.26 mL, 0.25 mmol) was added, and the mixture was stirred at room temperature for 4 hours. After completion of the stirring, 1 M hydrochloric acid (252 μL) was added, and the precipitated solid was filtered and washed with methanol to obtain 14.9 mg of the desired product as an orange solid (yield 27%).
