Trifluoroacetic acid (4 mL) was added to a solution of tert-butyl (3R,6S)-6-(2,3-difluorophenyl)-2-oxoazepan-3-ylcarbamate (82 mg, 0.241 mmol) in dichloromethane (4 mL). After 1 h, the solution was concentrated. Saturated aqueous sodium bicarbonate solution was added and the mixture was extracted with dichloromethane (3×). The combined organic extracts were washed with saturated brine, dried over magnesium sulfate, filtered and concentrated. MS 241.0 (M+1)
