Reaction Steps

To a sealed tube was charged a mixture of (2-{4,4-Dimethyl-9-oxo-7-thia-10-azatricyclo[6.4.0.02,6]dodeca-1(8),2(6)-dien-10-yl}-4-fluoro-6-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methyl Acetate 247b (100 mg, 0.19 mmol), 5-bromo-1-methyl-3-(4-(1-methylazetidin-3-yl)phenylamino)pyrazin-2(1H)-one 298d (68 mg, 0.19 mmol), PdCl2(dppf) (14 mg, 0.019 mmol), K3PO4 (60 mg), and NaOAc (30 mg) in MeCN (5 mL) and water (1 mL). It was heated at 110° C. for 2 h. The solvent was evaporated in vacuo and the residue was purified on reverse phase Combi-flash to give 298e (100 mg, 82%). MS: [M+H]+ 656.
