Procedure
From methyl 2-nitro-4-[(2-{1-[5-(4-trifluoromethylphenyl)-4-hydroxy-3-thienyl]ethylidene}hydrazino)carbonyl]benzoate (60.9 mg (0.12 mmol) and 0.2 M sodium hydroxide aqueous solution (1.26 mL, 0.25 mmol), 38.2 mg of the desired product was obtained in the same manner as in Synthetic Example 70 as a pale yellow solid (yield 65%).
