54.5 mg (0.20 mmol) of 1-(1-(4-tert-butylphenyl)-5-hydroxy-3-methyl-1H-pyrazol-4-yl)-ethanone and 40.0 mg (0.20 mmol) of 5-methoxycarbonyl-2-thiophenecarboxylic acid hydrazide were dissolved in 2.0 mL of DMF and stirred at 110° C. for 12 hours. After cooling, the solvent was removed by evaporation, and the crude product was washed with ethyl acetate and collected by filtration to obtain 32.0 mg of the desired product as a yellow solid (yield 35%).
