Reaction Steps

To a solution of 3-bromoazepan-2-one (1.398 g, 7.28 mmol) in tetrahydrofuran (10 ml), was added sodium hydride (0.48 g, 12.00 mmol) at 0° C. The mixture was stirred at 0° C. for 1 hour, and 1-(bromomethyl)-4-methoxybenzene (1.610 g, 8.01 mmol) was added. The mixture was warmed to room temperature over the span of 2 hours. The reaction was quenched with saturated aqueous ammonium chloride and extracted with ethyl acetate. The organic phase was washed with brine, dried and concentrated to afford crude product, which was purified by chromatography on silica gel (ethyl acetate/hexanes=2/8) to afford 3-bromo-1-(4-methoxybenzyl)azepan-2-one (1.403 g, 4.49 mmol, 61.7% yield). MS ESI: [M+H]+ m/z 313.2.
