To a sealed tube were added N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(6-chloro-5-(methylsulfonyl)pyridin-3-yl)acetamide 197-7 (30 mg, 0.07 mmol), 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine 183-2 (22 mg, 0.10 mmol), Pd(PPh3)4 (4 mg, 0.003 mmol), Na2CO3 (22 mg, 0.20 mmol), Toluene (0.4 mL), H2O (0.4 mL) and ethanol (0.1 mL). The reaction mixture was stirred at 100° C. overnight. After cooling to room temperature, the solvents were removed by rotary evaporation. The crude product was purified by reverse phase HPLC to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(2′-methyl-3-(methylsulfonyl)-2,4′-bipyridin-5-yl)acetamide 197.
