Procedure

4 M hydrogen chloride/EtOAc (10 ml) was added to an EtOAc (25 ml) solution of tert-butyl 4-{3-[1-(6-methyl-2-pyridinyl)-4-piperidinyl]propyl}-1-piperidinecarboxylate (1.3 g), followed by stirring overnight at room temperature. The reaction liquid was concentrated, then 2-propanol/diethyl ether was added thereto, followed by stirring. The precipitated solid was collected by filtration, and dried under reduced pressure to obtain 2-methyl-6-{4-[3-(4-piperidinyl)propyl]-1-piperidyl}pyridine dihydrochloride (1.1 g).
