Reaction Steps

To a sealed tube were added N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(6-chloro-5-fluoropyridin-3-yl)acetamide 190-5 (59 mg, 0.15 mmol), 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine 183-2 (49 mg, 0.23 mmol), Pd(PPh3)4 (9 mg, 0.08 mmol), Na2CO3 (79 mg, 0.75 mmol), Toluene (0.8 mL), H2O (0.8 mL) and ethanol (0.2 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-(3-fluoro-2′-methyl-2,4′-bipyridin-5-yl)acetamide 190.
