Reaction Steps

2-bromo-1-(3-bromophenyl)ethanone (4.0 g, 14.39 mmol) in anhydrous ether (50 mL) was added dropwise to a solution of pyrrolidine (2.05 g, 28.78 mmol) in anhydrous ether (20 mL) at 0° C. The reaction mixture was then warmed to room temperature. After stirring for 2 h, water (80 mL) was added and the aqueous layer was extracted with ethyl acetate (2×80 mL). The combined organic layers were dried over MgSO4 and concentrated to yield 1-(3-bromophenyl)-2-(1-pyrrolidinyl)ethanone as a light yellow oil (3.6 g, 94%), which was used without purification. MS (ES) m/e 268 [M+H]+.
