실험 절차

A mixture of 4-fluorophenylhydrazine (4.25 g, 33.7 mmol) and 2-(3-bromobenzoyl)-3-phenylaminoacrylonitrile (10.0 g, 30.7 mmol) in ethanol (100 ml) was heated at reflux under a nitrogen atmosphere. After 4 h, the reaction mixture was cooled to room temperature, diluted with hexane to give 5-amino-4-(3-bromobenzoyl)-1-(4-fluorophenyl)pyrazole (9.7 g) as a solid.
