Procedure

To a sealed tube was added N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(4-iodophenyl)acetamide 177-2 (520 mg, 1.1 mmol), 2-fluoropyridin-4-ylboronic acid 178-1 (237 mg, 1.6 mmol), Pd(PPh3)4 (65 mg, 0.055 mmol), saturated Na2CO3 (5 mL), ethanol (5 mL) and toluene (15 mL). The reaction was heated to 110° C. and stirred for 16 hours. The reaction was cooled down to room temperature, then extracted with ethyl acetate. The crude product was purified by silica-gel flash chromatography, eluted with ethyl acetate to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(4-(2-fluoropyridin-4-yl)phenyl)acetamide 178 as off-white solid.
