Procedure

1-[4-Hydroxy-5-(4-isobutylphenyl)-1-methyl-1H-pyrazol-3-yl]ethanone (0.179 mmol, 48.8 mg) and 4-hydrazinocarbonothioylaminobenzoic acid (0.179 mmol, 37.9 mg) were stirred with dimethylformamide (2.5 mL) and three drops of concentrated hydrochloric acid at room temperature for 24.5 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 (62.6 mg, yield 75%).
