실험 절차

A solution of di-tert-butyl [(3R,6S)-6-(2,3-difluorophenyl)-2-oxo-1-(1,3-thiazol-2-ylmethyl)azepan-3-yl]imidodicarbonate (0.481 g, 0.895 mmol) in DCM (10 mL) was treated with trifluoroacetic acid (3 mL). After 1 h the reaction was diluted with saturated aqueous sodium bicarbonate, the layers separated, and the aqueous phase extracted with DCM (2×). The organic washes were combined, dried over magnesium sulfate, and concentrated to afford the title compound (0.30 mg). MS 338.2 (M+1).
