실험 절차

Trifluoroacetic acid (3 mL) was added to a solution of tert-butyl (3R,6S)-6-(2,3-difluorophenyl)-2-oxo-1-(pyridin-2-ylmethyl)azepan-3-ylcarbamate (202 mg, 0.468 mmol) in dichloromethane (4 mL). After 18 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 332.2 (M+1).
