To a solution of 4-(diethylamino)piperidine dihydrochloride (3.0 g, 0.019 mmol) in water (20 mL), 2M sodium hydroxide solution (5.0 mL) was added at ambient temperature. The mixture was stirred for 30 min. The solvent was removed under reduced pressure, and methanol (10 mL) was added to the crude material, then the residue was removed by filtration. The filtrate was concentrated and dried to afford 4-(diethylamino)piperidine (1.7 g, y. 77%) as solid.
