To a 10 mL microwave tube was added (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[2-(3-fluoroazetidin-1-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-4-yl]methyl}-4-methyl-1,3-oxazolidin-2-one (INTERMEDIATE 22, 86 mg, 0.142 mmol), tert-butyl 4-(5-chloro-6-methylpyridin-3-yl)-3-methylbenzoate (INTERMEDIATE 39, 41 mg, 0.129 mmol), potassium phosphate (41 mg, 0.194 mmol), (2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2-aminoethyl)phenyl)]palladium(II) chloride (XPHOS Biphenyl Precatalyst) (20.3 mg, 0.026 mmol), followed by dioxane (2 mL) and water (0.1 mL). The tube was sealed and stirred at 180° C. in the microwave reactor for 10 minutes. After cooling down, the solvent was evaporated. The residue was purified by silica gel chromatography (0 to 100% Ethyl acetate/hexane) and afforded the title compound as a white solid in 46% yield. LCMS (M+H)+: 760.2.
