실험 절차
In ethanol (30 ml), 5-(2,4-dichlorophenyl)-2H-pyrazole-3-carboxylic acid hydrazide (136 mg) prepared in the Step 21-1-1 and 2,4-dihydroxybenzaldehyde (69 mg) was heated under reflux for 29 hours. Crystal appeared as the mixture was concentrated under a reduced pressure, the resulting crystal was separated by filtration, washed with ethanol, washed with ethyl acetate, and dried to give the title compound (129 mg, 66%).
