실험 절차

Trifluoroacetic acid (2 mL) was added to a solution of tert-butyl (3R,6S)-6-(2,3-difluorophenyl)-2-oxo-1-pyridin-4-ylazepan-3-ylcarbamate (55 mg, 0.132 mmol) in dichloromethane (2 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 318.2 (M+1).
