A reaction vessel was charged with the mixture of 1-(6-(5-bromo-1-methyl-2-oxo-1,2-dihydropyridin-3-ylamino)pyridin-3-yl)-4-methylpiperazin-2-one (332f) (0.3 g, 0.76 mmol),4-fluoro-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl acetate 210d (0.37 g, 0.76 mmol), PdCl2(dppf) (65 mg, 0.076 mmol), K3PO4 (325 mg, 1.53 mmol), and NaOAc (125 mg, 1.53 mmol) in MeCN (15 mL) and water (1 mL). It was then bubbled with argon for 15 min and heated at 110° C. for 3 h. After evaporation of solvent in vacuo, the residue was purified on silica-gel column eluting with 50:1 methylene chloride/methanol to afford 332g (0.4 g, 63%). MS: [M+H]+ 668.
