실험 절차

1-[5-(4-tert-Butylphenyl)-1-ethyl-4-hydroxy-1H-pyrazol-3-yl]ethanone (0.1718 mmol, 49.2 mg) and 4-hydrazinocarbonothioylaminobenzoic acid (0.1718 mmol, 36.3 mg) were stirred with dimethylformamide (3 mL) and two drops of concentrated hydrochloric acid at room temperature for 21 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 yellow solid (59 mg, yield 72%).
