Sodium hydride (60% dispersion in mineral oil; 17.6 mg, 0.264 mmol) was added to a solution of tert-butyl (3R,6S)-6-(2,3-difluorophenyl)-2-oxoazepan-3-ylcarbamate (75 mg, 0.220 mmol) in N,N-dimethyl formamide (2 mL) at 0° C. After 5 min, 2-bromoethyl methyl ether (0.025 mL, 0.264 mmol) was added and the mixture was allowed to warm to ambient temperature. After 3 h, the reaction was quenched with water and the mixture was extracted with ethyl acetate. The organic layer was washed with water (2×), saturated brine, dried over magnesium sulfate, filtered and concentrated to give the title compound. MS 421 (M+Na).
