A solution of azepan-2-one (5.0 g, 44 mmol) and trimethyloxonium tetrafluoroborate (7.8 g, 53 mmol) in DCM (30 mL) was stirred at room temperature for 12 h. Then the reaction mixture was quenched with saturated sodium carbonate (50 mL) and extracted with DCM (3×100 mL). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated to give the desired product. MS (ESI): 128 (MH+).
