실험 절차
1.0712 g (4.21 mmol) of the 1-(4-tert-butylphenyl)-5-hydroxy-3-methyl-1H-pyrazole-4-carbaldehyde synthesized in 1) and 819.6 mg (4.22 mmol) of 4-methoxycarbonylbenzhydrazide were stirred in 10 ml of dimethylformamide at room temperature for 3 hours. After the solvent was removed by evaporation, the precipitated solid was washed with a small amount of methanol and dried to obtain 765.9 mg of the above-identified desired product as a yellow solid (yield 42%).
