(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[5-bromo-2-(methylsulfanyl)pyrimidin-4-yl]methyl}-4-methyl-1,3-oxazolidin-2-one (INTERMEDIATE 45) (307 mg, 0.579 mmol), methyl 3-[4-methoxy-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]propanoate (INTERMEDIATE 2) (185 mg, 0.579 mmol), 1,1bis(di-tert-butylphosphino)ferrocene palladium dichloride (39.4 mg, 0.058 mmol), potassium carbonate (0.724 ml, 1.447 mmol) and THF (5 mL) were sealed in a uw vessel and subject to microwave irradiation at 140° C. for 20 min. The reaction crude was dried over Na2SO4, filtered and purified by preparative TLC (silica gel) developed with EtOAc/hexanes (40% ethyl acetate v/v) to give a brown solid as the titled compound. LCMS calc.=643.16. found=644.17 (M+H)+.
