Reaction Steps

To a solution of (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 (Example 123) (40 mg, 0.0676 mmol) in CHCl3 (1 mL) that had been degassed with N2 was added methyl disulfide (10 μL, 0.101 mmol) and t-butyl nitrite (16 μL, 0.135 mmol). The reaction was stirred at room temperature for 30 minutes and then heated to reflux for 2 hours. The reaction was then cooled to room temperature and diluted with hexanes (3 mL). The solution was loaded directly onto a silica gel column and eluted with 25% EtOAc/hexanes. Fractions containing the desired product were combined and repurified by silica gel chromatography with 5 to 25% EtOAc/hexanes to afford (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[2′-methoxy-5′-(methylthio)-4-(trifluoromethyl)biphenyl-2-yl]methyl}-4-methyl-1,3-oxazolidin-2-one. Rf=0.52 (40% EtOAc/hexanes). LCMS=624.1 (M+1)+. 1H NMR (CDCl3, 600 MHz, rotamers present) δ 6.94-7.85 (m, 9H), 5.58 (d, J=8.1 Hz) 5.25 (d, J=7.8 Hz), 4.94 (d, J=15.8 Hz), 4.85 (d, J=15.7 Hz), 3.65-4.12 (m, 5H), 2.47 (s), 2.44 (s), 0.54 (d, J=6.6 Hz), 0.40 (d, J=6.6 Hz).
