Hydrochloric Acid → 4-(4-Chlorophenyl)-4-methoxypiperidine

Participants

Reaction Steps

To a solution of 1-tert-butoxycarbonyl-4-(4-chlorophenyl)-4-methoxypiperidine (0.72 g) in ethyl acetate (10 ml) was added 4N HCl in ethyl acetate (5.5 ml). After stirring for 6.7 hours, the reaction mixture was poured into a mixture of ethyl acetate and water, followed by alkalification of the solution to pH 12. The organic layer was successively washed with water and brine and dried over magnesium sulfate. The solvent was evaporated in vacuo to give 4-(4-chlorophenyl)-4-methoxypiperidine (0.39 g).
