실험 절차

A mixture of 4-hydrazinobenzoic acid (5.0 g, 32.9 mmol) and cyclohexanone (3.3 g, 33 mmol) in 30 mL of acetic acid was heated under reflux for 4 hours, then cooled, diluted with water and acidified with HCl. The resultant solid was collected by filtration, washed with water and dried to give 3.6 g of the title compound as a crystalline solid.
