30.5 mg (0.11 mmol) of 1-(1-(4-tert-butylphenyl)-5-hydroxy-3-methyl-1H-pyrazol-4-yl)-ethanone and 23.1 mg (0.11 mmol) of 4-methoxycarbonylbenzhydrazide were dissolved in 3.0 ml of DMF and stirred at 100° C. for 3 hours. After cooling and evaporation of the solvent, the crude product was recrystallized from ethyl acetate/n-hexane to give 32.9 mg of the desired product as a yellow solid (yield 66%).
