実験手順

From 1-[5-(3,4-dichlorophenyl)-4-hydroxy-1-methyl-1H-pyrazol-3-yl]ethanone (0.70 mmol, 200 mg) synthesized in Synthetic Example 1, methyl 2-nitro-4-hydrazinocarbonylbenzoate (0.70 mmol, 167.8 mg) of Reference Synthetic Example 40 and tosylic acid monohydrate (36.2 mg, 0.21 mmol), 311.1 mg of the desired product was obtained in the same manner as in Synthetic Example 58 as a yellow solid (yield 88%).
