Procedure

A mixture of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[2-iodo-5-(trifluoromethyl)benzyl]4-methyl-1,3-oxazolidin-2-one (50 mg; 0.084 mmol), (4-fluoro-5-isopropyl-2-methoxyphenyl)boronic acid (EXAMPLE 78, 22 mg; 0.105 mmol), palladium acetate (6 mg; 0.0103 mmol), and potassium carbonate (29 mg; 0.257 mmol) in 5:1 acetone/water (6 mL) was heated at reflux for 1 h. Acetone was removed in vacuo and the residue was diluted with H2O (10 mL) and extracted with CH2Cl2 (3×10 mL). The combined extracts were washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated in vacuo. The residue was purified by flash chromatography (0-25% EtOAc/hexanes gradient) to afford (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[4′-fluoro-5′isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}-4-methyl-1,3-oxazolidin-2-one as a clear glass. This product can also be made by the method provided in Example 372.
