Reaction Steps
A solution of 2-(4-bromophenyl)pyrrolidine (2.26 g, 10 mmol) in dioxane (18 mL) and water (12 mL) was added potassium carbonate (5.52 g, 40 mol) and benzyl chloroformate (1.88 g, 11 mmol) at ambient temperature and stirred overnight. Then the mixture was partitioned between ethyl acetate and brine. The organic phase was concentrated in vacuo and the residue was purified by column chromatography (silica gel, EtOAc:hexane=1:10) to give the title compound (2.95 g, 82%) as a colorless oil. LC-MS (ESI) m/z: 360 (M+1)+.
