Procedure

t-Butyl nitrite (90%, 6.5 mg, 8.3 μL, 0.0627 mmol) was added to a suspension of (4S,5R)-3-{[5-amino-3-(4-fluoro-5-isopropyl-2-methoxyphenyl)-2-naphthyl]methyl}-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one (19.9 mg, 0.0314 mmol) in CH2I2 (1 mL). Dry CHCl3 (0.5 mL) was added to dissolve the precipitate formed. The solution was heated at 80° C. for 5 h. The reaction mixture was concentrated in vacuo and the resulting slurry was purified by flash chromatography (Si, 12×160 mm, 0-20% EtOAc in hexanes gradient) to afford (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[3-(4-fluoro-5-isopropyl-2-methoxyphenyl)-5-iodo-2-naphthyl]methyl}-4-methyl-1,3-oxazolidin-2-one. Rf=0.47 (20% EtOAc/hexanes).
