Trifluoroacetic acid → (3R,6S)-3-Amino-6-(2,3-difluorophenyl)-1-(1,3-thiazol-2-ylmethyl)azepan-2-one

Participants

Reaction Steps

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 lh 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).
