実験手順

From methyl 5-[(2-{1-[5-(3,4-dichlorophenyl)-4-hydroxy-1-methyl-1H-pyrazol-3-yl]ethylidene}hydrazino)carbonyl]-2-thiophenecarboxylate (200 mg, 0.43 mmol) and 1 M sodium hydroxide aqueous solution (2.13 mL, 2.13 mmol), 153.3 mg of the desired product was obtained in the same manner as in Synthetic Example 58 as a yellow solid (yield 84%).
