Procedure

To a sealed tube were added N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(3-chloro-2′-methyl-2,4′-bipyridin-5-yl)acetamide 184 (46 mg, 0.10 mmol), zinc cyanide (14 mg, 0.12 mmol), Pd2(dba)3 (9 mg, 0.010 mmol), Q-phos (9 mg, 0.022 mmol) and 1 ml DMF/H2O (99/1, v/v). The reaction mixture was bubbled with nitrogen for 1 minute and stirred at 130° C. overnight. After cooling to room temperature, the solvents were evaporated and the crude product was purified by reverse phase HPLC to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(3-cyano-2′-methyl-2,4′-bipyridin-5-yl)acetamide 188.
