실험 절차
1-Acetyl-4-chlorocarbonylpiperazine can be prepared by the action of phosgene (9.9 g.) on 1-acetylpiperazine (25.6 g.) in anhydrous toluene (75 cc.) for 1 hour at 2° C. The 1-acetylpiperazine hydrochloride formed during the reaction is filtered off and washed with anhydrous toluene (50 cc.). The toluene filtrate is evaporated to dryness under reduced pressure (20 mm.Hg) to give 1-acetyl-4-chlorocarbonylpiperazine (14.0 g.) in the form of an oil.
