A mixture of 5-bromo-3-(6-methyl-1H-benzimidazol-2-yl)pyrazin-2-amine (100 mg, 0.3288 mmol), 1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one (154.6 mg, 0.6578 mmol), potassium carbonate (136.4 mg, 0.9867 mmol) and [1,1-bis(diphenylphosphino)ferrocene]dichloropalladium (26.86 mg, 0.03289 mmol) in DMF (3 mL) were heated to 110° C. for 2 hours. The mixture was diluted with EtOAc, washed with water, and the organic layer concentrated in vacuo. The resulting residue was purified by reverse phase preparative HPLC [Waters Sunfire C18, 10 uM, 100A column, gradient 10%-95% B (solvent A: 0.05% TFA in water, solvent B: CH3CN) over 16 minutes at 25 mL/min]. The fractions were collected and freeze-dried to give the title compound (47.4 mg, 40% Yield). MS (ES+) 333
