A 100-mL round-bottomed flask equipped with a reflux condenser was charged with 4-chloro-2-(4-oxo-7,8,9,10-tetrahydropyridazino[4,5-a]indolizin-3(4H)-yl)nicotinaldehyde 192c (196 mg, 0.60 mmol), (S)-1-methyl-3-(5-(2-methyl-4-(oxetan-3-yl)-piperazin-1-yl)pyridin-2-ylamino)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 191j (290 mg, 0.60 mmol), sodium acetate (100 mg, 1.2 mmol), K3PO4 (320 mg, 1.2 mmol), PdCl2(dppf) (50 mg, 0.060 mmol), acetonitrile (25 mL), and water (1 mL). After bubbling nitrogen through the mixture for 30 minutes, it was heated at 100° C. for 3 hours under N2 protection. The reaction mixture was cooled to room temperature and evaporated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 20:1 methylene chloride/methanol to afford 192d 173 mg, 44%) as a brown solid. MS-ESI: [M+H]+ 648.4.
