실험 절차

A mixture of 4-fluorophenylhydrazine (26.6 g, 211 mmol) and 2-(3-iodobenzoyl)-3-phenylaminoacrylonitrile (79 g, 211 mmol) in ethanol (400 ml) was heated at reflux under a nitrogen atmosphere. After 30 minutes, the reaction mixture was cooled to room temperature, diluted with hexane to give 5-amino-4-(3-iodobenzoyl)-1-(4-fluorophenyl)pyrazole (75.1 g) as a solid.
