Reaction Steps

To a solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-3-[2-(1H-pyrrol-3-yl)-5-(trifluoromethyl)benzyl]-1,3-oxazolidin-2-one (6.8 mg, 0.0127 mmol) (Example 120) in DMSO (300 μL) was added powdered KOH (3.6 mg, 0.0643 mmol). After stirring for 15 minutes, 2-iodopropane (3.2 μL, 0.032 mmol) was added. After 1.5 hours of stirring at room temperature, water (5 mL) was added, and the mixture was extracted, first with CH2Cl2 (2×15 mL) and then with EtOAc (2×15 mL). The combined organics were dried over Na2SO4, filtered, and concentrated. Purification of the residue by PTLC (25% EtOAc/hexanes) afforded (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[2-(1-isopropyl-1H-pyrrol-3-yl)-5-(trifluoromethyl)benzyl]-4-methyl-1,3-oxazolidin-2-one. Rf=0.33 (25% EtOAc/hexanes). LCMS=579.2 (M+1)+. 1H NMR (CDCl3, 500 MHz) δ 7.85 (s, 1H), 7.71 (s, 2H), 7.61 (s, 1H), 7.56 (d, J=8.0 Hz, 1H), 7.50 (d, J=8.0 Hz, 1H), 6.83 (t, J=2.1 Hz, 1H), 6.79 (t, J=2.5 Hz, 1H), 6.24 (t, J=2.3 Hz, 1H), 5.49 (d, J=8.0 Hz, 1H), 5.04 (d, J=15.5 Hz, 1H), 4.48 (d, J=15.6 Hz, 1H), 4.27 (m, 1H), 3.76 (m, 1H), 1.48 (d, J=6.6 Hz, 6H), 0.49 (d, J=6.6 Hz, 3H).
