Procedure

A 100-mL single-neck round-bottomed flask was charged with 2-bromo-4-fluoro-6-(1-oxo-3,4,6,7,8,9-hexahydropyrido[3,4-b]indolizin-2(1H)-yl)benzyl acetate 101h (120 mg, 0.27 mmol), (S)-3-(5-(2-ethyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)-1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 122a (158.4 mg, 0.32 mmol), Pd(dppf)Cl2 (24.5 mg, 0.03 mmol), K3PO4 (114.5 mg, 0.54 mmol), sodium acetate.trihydrate (73.4 mg, 0.54 mmol), water (0.5 mL), and acetonitrile (20 mL). The system was evacuated and refilled with N2. The reaction mixture was heated at 100° C. for 2 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 25:1 dichloromethane/methanol to afford 123a (105 mg, 53%) as a yellow brown solid. MS: [M+H]+ 724.3.
