Reaction Steps

To a solution of 3-[(4-bromophenoxy)methyl]azetidine (220 mg, 0.91 mmol) in CH2Cl2 (10 mL) was added triethylamine (276 mg, 2.73 mmol) and acetic anhydride (186 mg, 1.82 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was concentrated in vacuo to give a yellow oil. The crude product was diluted with ethyl acetate (20 ml), washed with 1N HCl followed by saturated aqueous sodium bicarbonate solution, dried over sodium sulfate, and concentrated to give 1-{3-[(4-bromophenoxy)methyl]azetidin-1-yl}ethanone (233 mg, 100%) as a colorless oil. 1H NMR (400 MHz, CDCl3) δ 7.38 (d, 2H), 6.78 (d, 2H), 4.28 (m, 1H), 4.24-4.00 (m, 4H), 3.87 (m, 1H), 3.07 (m, 1H), 1.90 (s, 3H)
