Reaction Steps

To a solution of [(1S,2S)-2-(3,5-difluorophenyl)-2-hydroxy-1-methylethyl]carbamate (900 mg, 2.80 mmol) in THF (28.6 mL) was added MeOH (14.3 mL) and 7.5 N KOH (7.2 mL). The reaction was stirred at room temperature for 4 hours and then extracted with EtOAc (2×75 mL). The organic extracts were washed with water and brine (50 mL each), dried over Na2SO4, filtered, and concentrated. Purification of the residue by flash chromatography on silica gel (10 to 75% EtOAc/hexanes) afforded (4S,5S)-5-(3,5-difluorophenyl)-4-methyl-1,3-oxazolidin-2-one. Rf=0.07 (25% EtOAc/hexanes). LCMS=214.3 (M+1)+. 1H NMR (CDCl3, 500 MHz) δ 6.89-6.93 (m, 2H), 6.82 (m, 1H), 6.24 (bs, 1H), 5.01 (d, J=6.8 Hz, 1H), 3.79 (m, 1H), 1.42 (d, J=6.2 Hz, 3H).
