1-[5-(4-t-Butylphenyl)-4-hydroxy-1-methyl-1H-pyrazol-3-yl]ethanone (0.228 mmol, 62 mg), 4-(hydrazinocarbonyl)-N-methylbenzenesulfonamide (0.228 mmol, 52 mg) and p-tosylic acid monohydrate (30 mol %, 11.8 mg) were dissolved in isopropyl alcohol (6 mL) and stirred at 100° C. for 19 hours. Then, the solvent was evaporated, and the residue was purified by silica gel thin layer chromatography (chloroform/methanol=10/1) to give the desired product as a yellow solid (30.3 mg, yield 28%).
