Procedure

To a solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-3-{[2-(methylsulfanyl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-4-yl]methyl}-1,3-oxazolidin-2-one (INTERMEDIATE 21, 2.0 g, 3.46 mmol), 4-(5-bromo-4-methylthiazol-2-yl)-3-methylbenzoic acid (INTERMEDIATE 42, 1.190 g, 3.81 mmol), potassium phosphate (2.2 g, 10.39 mmol) in THF (5 mL) and water (5 mL) was added tetrakis(triphenylphosphine)palladium(0) (0.400 g, 0.346 mmol). It was degassed, and refilled with nitrogen. The reaction mixture was heated to reflux for 2 hours to see complete conversion by LCMS. It was distributed between 100 mL of water and 300 mL of ethyl acetate. The organic layer was dried over sodium sulfate, filtered and the filtrate concentrated. The crude was purified on a silica gel column, eluting with 30% ethyl acetate in hexanes to give the title compound as white solid (2.2 g, 93% yield). LCMS (M+H)+: 683.0
