Procedure
To a mixture of tert-butyl 4-(3-(4-bromophenoxy)propyl)piperazine-1-carboxylate (200 mg, 0.50 mmol) in ethyl acetate (10 mL) was added HCl/ethyl acetate (20 mL). The mixture was stirred at rt for 4 hours. The mixture was concentrated to give the title compound (150 mg, 100% yield) as a white solid.
