Reaction Steps

To a solution of 1-(4-bromophenyl)ethanone (500 mg, 2.5 mmol) in ethanol (16 mL) was added cyclopentanamine (320 mg, 3.8 mmol) and the reaction mixture was heated at 50° C. for 18 h. The reaction mixture was cooled to 0° C. and sodium borohydride (140 mg, 3.8 mmol) was added and the reaction mixture was warmed to room temperature and stirred for 30 min. The reaction mixture was quenched with 2 M aqueous ammonium hydroxide and extracted with methylene chloride. The combined organic layers were dried over sodium sulfate, filtered and concentrated to afford the desired product (600 mg, 90%) as a red oil: ESI MS m/z 269 [C13H18BrN+H]+.
