Into a Parr pressure reactor were charged 3-bromo-N-((2-methylpyrimidin-5-yl)methyl)-5-(pyrrolidine-1-carbonyl)benzamide (240 mg, 0.48 mmol), 5-methyl-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (160 mg, 0.58 mmol) (WO 2008/130481), toluene (5 mL), ethanol (1 mL), cesium carbonate (170 mg, 0.52 mmol), and water (0.5 mL). The mixture was degassed and purged with nitrogen several times and then tetrakis(triphenylphosphine)palladium(0) (28 mg, 0.024 mmol) was added. The tube was sealed and the mixture was heated at 90° C. overnight. After cooling, the mixture was filtered through Celite and the filtrate was concentrated. The residue was purified via flash chromatography and then preparative HPLC to afford the desired product as a white solid.
