Procedure

To a 0° C. solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[2-[4-(1-hydroxyethyl)-1,3-thiazol-2-yl]-5-(trifluoromethyl)benzyl]-4-methyl-1,3-oxazolidin-2-one (Example 134) (31.0 mg, 0.052 mmol) in CH2Cl2 (6 mL) was added DMP (55 mg, 0.130 mmol). The reaction was warmed to room temperature and stirred for 45 minutes. Next, the reaction was diluted with EtOAc (40 mL) and washed with 1N NaOH (2×15 mL) and brine (2×15 mL). The organic layer was dried over Na2SO4, filtered, and concentrated. Purification of the residue by flash chromatography on silica gel (40% EtOAc/hexanes) afforded (4S,5R)-3-[2-(4-acetyl-1,3-thiazol-2-yl)-5-(trifluoromethyl)benzyl]-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one. Rf=0.26 (40% EtOAc/hexanes). LCMS=597.1 (M+1)+. 1H NMR (CDCl3, 600 MHz) δ 8.27 (s, 1H), 7.89 (s, 1H), 7.77-7.82 (m, 4H), 7.71 (d, J=7.9 Hz, 1H), 5.68 (d, J=7.9 Hz, 1H), 5.22 (d, J=16.3 Hz, 1H), 4.85 (d, J=16.4 Hz, 1H), 4.08 (m, 1H), 2.70 (s, 3H), 0.71 (d, J=6.6 Hz, 3H).
