실험 절차
N-[4-(Trifluoromethyl)phenyl]-2-(ethoxymethylene)acetoacetamide (1 g) in 3 mL of ethanol is stirred overnight with 0.3 g of hydrazine hydrate. The precipitate is collected by vacuum filtration, washed with ethanol:water 2:1 and dried to give 0.3 g of 3-methyl-4-[4-(trifluoromethyl)phenylaminocarbonyl]pyrazole as an off-white solid.
