실험 절차
A solution of ethyl 4-(2,4-dibenzyloxyphenyl)-2,4-dioxobutanoate (3.23 g) in ethanol (10 mL) is treated with hydrazine hydrate (0.4 mL), refluxed for 2 hours and then cooled to room temperature. The mixture is filtered to yield ethyl 3-(2,4-dibenzyloxyphenyl)-pyrazole-5-carboxylate as a solid (1.5 g).
