実験手順

1-[4-Hydroxy-1-methyl-5-(3-trifluoromethylphenyl)-1H-pyrazol-3-yl]ethanone (0.229 mmol, 65.0 mg) and 4-hydrazinocarbonothioylaminobenzoic acid (0.229 mmol, 48.3 mg) were stirred with dimethylformamide (2.5 mL) and three drops of concentrated hydrochloric acid at room temperature for 24 hours. After addition of water, the precipitated yellow solid was recovered by filtration, washed with water and dried by means of a vacuum pump. Chloroform/n-hexane was added to the resulting solid, and the precipitated solid was recovered by filtration and dried by means of a vacuum pump to give the desired product as a yellow solid (74.7 mg, yield 68%).
