Procedure

To a solution of tert-butyl 4-methoxy-4-(1-methyl-1H-imidazol-2-yl)piperidine-1-carboxylate (182 mg) in EtOAc (0.7 ml) and water (0.09 ml) was added 4N hydrogen chloride in EtOAc (0.7 ml) and the mixture was stirred at room temperature for 2 hours. Solvent was removed in vacuo to give 4-methoxy-4-(1-methyl-1H-imidazol-2-yl)piperidine dihydrochloride (122 mg) as a colorless powder. The obtained crude product was used in next reaction without further purification.
