1-(2-methoxy-4-(1-Boc-4-piperidyloxy)phenylacetyl)-4-(2-methylphenyl)piperazine-2-carboxamide (423 mg, 0.75 mmol) was stirred in ethyl acetate (4 ml) in an ice bath under nitrogen. A cold, saturated solution (4 ml) of HCl in ethyl acetate was added and the mixture stirred in the cold for 45 min. Nitrogen gas was passed through the mixture for 1 hour, and the reaction was concentrated in vacuo. The residue was reconcentrated from methanol and from ether to give 1-(2-methoxy-4-(4-piperidyloxy)phenylacetyl)-4-(2-methylphenyl)piperazine-2-carboxamide dihydrochloride.
