Reaction Steps

A mixture of Example 135D (170 mg, 0.45 mmol), N-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine (105 mg, 0.45 mmol), bis(triphenylphosphine)palladium(II) chloride (31 mg, 0.045 mmol), tricyclohexylphosphine (13 mg, 0.045 mmol) and cesium carbonate (443 mg, 1.34 mmol) in a round bottom flask was purged with nitrogen. Dioxane (10 mL) was added and the mixture was heated at 100° C. overnight. After cooling, the mixture was triturated with dichloromethane (200 mL) and filtered. The filtrate was concentrated and the residue was separated by flash chromatography on silica gel (Teledyne CombiFlash Rf, 40% to 100% ethyl acetate in hexane) to provide the title compound. MS (ESI+) m/z 406 (M+1).
