A solution of (4S,5R)-3-{[6-azetidin-1-yl-3-(5-iodo-2-methoxyphenyl)pyridin-2-yl]methyl}-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one (20 mg, 0.029 mmol) and [5-(methoxycarbonyl)-2-furyl]boronic acid (14.75 mg, 0.087 mmol) in THF (0.5 mL) was degassed with N2 at 25° C. 1N K2CO3 (0.5 mL) was added followed by 1,1-bis(di-tert-butylphosphino)ferrocene palladium dichloride (1.885 mg, 2.89 μmol) and the reaction was stirred vigorously at 25° C. under N2 overnight. The reaction was diluted with water and extracted with EtOAc (3×). The combined extracts were dried (Na2SO4) and concentrated in vacuo to afford the crude product. This was purified by preparative TLC (20×20, 1000 μm, hexanes/EtOAc (70/30)) to give methyl 5-{3-[6-azetidin-1-yl-2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)pyridin-3-yl]-4-methoxyphenyl}-2-furoate.
