Procedure

4 M hydrogen chloride/EtOAc (4 ml) was added to an EtOAc (9 ml) solution of tert-butyl 4-(2-{3-[(aminocarbonyl)amino]phenyl}ethyl)-1-piperidinecarboxylate (227 mg), followed by stirring at room temperature for 3 hours. The solvent was evaporated under reduced pressure to obtain 1-{3-[2-(4-piperidyl)ethyl]phenyl}urea hydrochloride (185 mg).
