実験手順

From methyl 5-[(2-{1-[5-(3,4-dichlorophenyl)-4-hydroxy-3-thienyl]ethylidene}hydrazino)carbonyl]-2-thiophenecarboxylate (56.3 mg, 0.12 mmol) and 0.2 M sodium hydroxide aqueous solution (1.89 mL, 0.38 mmol), 7.5 mg of the desired product was obtained in the same manner as in Synthetic Example 66 as a pale yellow solid (yield 14%).
