実験手順

1-[5-(4-n-Pentylphenyl)-1-methyl-4-hydroxy-1H-pyrazol-3-yl]ethanone (0.2381 mmol, HPLC purity 86.3%, 79.0 mg) and 4-hydrazinocarbonothioylaminobenzoic acid (0.2381 mmol, 50.3 mg) were stirred with dimethylformamide (3 mL) and three drops of concentrated hydrochloric acid at room temperature for 8.5 hours. After addition of water, the precipitated yellow solid was recovered by filtration, washed with water and dried by means of a vacuum pump. The resulting solid was stirred with chloroform/n-hexane for a while, then recovered by filtration and dried by means of a vacuum pump to give the desired product as a pale yellow solid (86.4 mg, yield 76%).
