Reaction Steps

To a 0° C. solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[2-(3-methoxy-6-methylpyridin-2-yl)-5-(trifluoromethyl) benzyl]-4-methyl-1,3-oxazolidin-2-one (Example 174) (7.6 mg, 0.0128 mmol) in CH2Cl2 (1.3 mL) was added m-CPBA (5.8 mg, 77% purity, 0.0256 mmol). The reaction was stirred at room temperature for 1 hour and then diluted with CH2Cl2 (10 mL), washed with aq. NaHSO3, saturated K2CO3, and brine (5 mL each). The organic layer was dried over Na2SO4, filtered, and concentrated. Purification of the residue by PTLC (50% Et2O/CH2Cl2) afforded the title compound. Rf=0.23 (50% Et2O/CH2Cl2). LCMS=609.2 (M+1)+. 1H NMR (CDCl3, 500 MHz) δ 7.85 (s, 1H), 7.78 (d, J=7.7 Hz, 1H), 7.70 (s, 2H), 7.62 (s, 1H), 7.53 (d, J=7.8 Hz, 1H), 7.32 (d, J=8.9 Hz, 1H), 7.04 (d, J=9.2 Hz, 1H), 5.74 (d, J=8.3 Hz, 1H), 4.88 (d, J=14.8 Hz, 1H), 4.11-3.96 (m, 1H), 3.88 (d, J=14.9 Hz, 1H), 3.86 (s, 3H), 2.49 (s, 3H), 0.65 (d, J=6.6 Hz, 3H).
