Reaction Steps

To a solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[4′-fluoro-3′-isopropenyl-4-(trifluoromethyl)biphenyl-2-yl]methyl}-4-methyl-1,3-oxazolidin-2-one (Example 119) (18.8 mg, 0.031 mmol) in EtOH (4.5 mL) was added 10% Pd/C (15 mg). The reaction was placed under a H2 atmosphere (balloon) and stirred vigorously. After 45 minutes, the catalyst was removed by filtration. The filtrate was concentrated, and the residue was purified by flash chromatography on silica gel with 15% EtOAc/hexanes. Further purification by PTLC with 75% CH2Cl2/hexanes afforded (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[4′-fluoro-3′-isopropyl-4-(trifluoromethyl)biphenyl-2-yl]methyl}-4-methyl-1,3-oxazolidin-2-one. Rf=0.35 (15% EtOAc/hexanes). LCMS=608.2 (M+1)+. 1H NMR (CDCl3, 500 MHz) δ 7.86 (s, 1H), 7.71 (s, 1H), 7.70 (s, 2H), 7.64 (d, J=8.0 Hz, 1H), 7.41 (d, J=8.0 Hz, 1H), 7.15 (m, 1H), 7.08-7.12 (m, 2H), 5.52 (d, J=8.0 Hz, 1H), 4.89 (d, J=15.7 Hz, 1H), 4.18 (d, J=15.8 Hz, 1H), 3.76 (m, 1H), 3.28 (m, 1H), 1.25-1.29 (m, 6H), 0.42 (d, J=6.4 Hz, 3H).
