Versuchsvorschrift

A sample of 30.9 g of 1-acetyl-4-(4-bromobenzoyl)piperidine is refluxed for 6 hours in 6N HCl, cooled, and the resulting insoluble salt is collected. The salt is recrystallized from an ethanol-ether mixture, then from isopropanol to give off-white crystals, mp 225°-227° C., 4-(4-bromobenzoyl)piperidine hydrochloride.
