Reaction Steps

A mixture of 114e (440 mg, 1.79 mmol), 3,5-dibromo-1-methylpyridin-2(1H)-one (534 mg, 2.0 mmol), Pd2(dba)3 (83 mg, 0.091 mmol), Xantphos (105 mg, 0.182 mmol) and Cs2CO3 (1.48 g, 4.55 mmol) in DMF (10 mL) was stirred at 95° C. under N2 for 7 h. The mixture was diluted with EA and filtered. The filtrate was washed with water, dried over Na2SO4, filtered and concentrated. The residue was purified by silica gel chromatography (PE/EA=1/2) to give (S)—N-(1-(6-(5-bromo-1-methyl-2-oxo-1,2-dihydropyridin-3-ylamino)pyridin-2-yl)piperidin-3-yl)acrylamide 114f (220 mg, 28%) as yellow solid. MS-ESI: [M+H]+ 433.3
