Procedure

N-(3-Chloropropyl)-piperidine hydrochloride (97% purity from Aldrich Chemicals) (100 g) was dissolved in water (150 mL) and saturated aqueous potassium carbonate (250 mL) was slowly added to it. Also, 10N sodium hydroxide (25 mL) and diethyl ether (250 mL) were added and the mixture was stirred for one hour. The layers were separated; the organic layer was dried over anhydrous potassium carbonate and concentrated on a Büchi Labortechnik AG Rotavapor® evaporator to give the title compound (77.2 g, 94.4%), which was used without purification for the next reactions.
