Procedure
A mixture of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[(3-iodo-5-nitro-2-naphthyl)methyl]-4-methyl-1,3-oxazolidin-2-one (34.0 mg, 0.0545 mmol), (4-fluoro-5-isopropyl-2-methoxyphenyl)boronic acid (23.1 mg, 0.0109 mmol), and 1,1′-bis(di-t-butylphosphinoferrocene)palladium dichloride (3.5 mg, 0.00545 mmol) in 1N aqueous potassium carbonate (2 mL) and THF (2 mL) was heated at 85° C. in a sealed tube for 2 h. The reaction mixture was cooled to room temperature and water (10 mL) was added. The mixture was extracted with EtOAc (3×20 mL) and the combined organic extracts were dried (Na2SO4) and concentrated in vacuo to give the crude product. This was purified by flash chromatography (Si, 12×160 mm, 0-30% EtOAc in hexanes gradient) to afford (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[3-(4-fluoro-5-isopropyl-2-methoxyphenyl)-5-nitro-2-naphthyl]methyl}-4-methyl-1,3-oxazolidin-2-one. Rf=0.23 (20% EtOAc/hexanes).
