Procedure

To a solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[2′-methoxy-5′-nitro-4-(trifluoromethyl)biphenyl-2-yl]methyl}-4-methyl-1,3-oxazolidin-2-one (example 122) (48.2 mg, 0.077 mmol) in EtOAc (4 mL) was added PtO2 (12 mg) and the reaction was placed under an atmosphere of hydrogen (balloon) and stirred vigorously. After 45 minutes, the catalyst was removed by filtration through a plug of silica gel with 100% EtOAc. The filtrate was concentrated to afford (4S,5R)-3-{[5′-amino-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one. Rf=0.20 (40% EtOAc/hexanes). LCMS=593.2 (M+1)+. 1H NMR (CDCl3, 500 MHz, rotamers present) δ 7.85 (s, 1H), 7.60-7.70 (m, 4H), 7.36 (d, J=7.8 Hz, 1H), 6.74-6.84 (m, 2H), 6.56 (s, 1H), 5.45-5.54 (m, 1H), 4.82-4.87 (m, 1H), 3.64-4.17 (m, 2H), 3.70 (s, 3H), 0.43-0.53 (m, 3H).
