To a stirring solution of 1-(3-methoxy-phenyl)-pyrrolidine (354 mg, 2 mmol) in dichloromethane (30 ml) at 0° C. was added BBr3 (4.0 ml, 4 mmol, 1 M solution in dichloromethane) in a dropwise fashion. The resulting solution was stirred over night at room temperature and then poured into ice water (30 ml). The aqueous mixture was extracted with dichloromethane (3×). The combine organic layers were washed with brine (1×), dried over sodium sulfate, and filtered. The dichloromethane filtrate was concentrated to afford the title compound as an oil (317 mg, 97%). MS(ES) m/e 164.2 ([M+H]+).
