실험 절차

To a solution of 1-acetyl-4-aminopiperazine dihydrochloride (300 mg) in ethanol (10 ml) and triethylamine (0.78 ml) was added p-fluorobenzaldehyde (0.164 ml), and the mixture was heated at 80° C. for 2 hours. After removal of the solvent in vacuo, the residue was triturated with ethyl acetate and water. The organic layer was separated, dried over magnesium sulfate, and concentrated. The residue was crystallized from diisopropyl ether to give 1-acetyl-4-(4-fluorobenzylidene)aminopiperazine (0.15 g).
