반응 단계

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 4-chloro-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridine-3-carbaldehyde 108a (105 mg, 0.30 mmol), 1-methyl-3-({5-[(2R)-2-methyl-4-(oxetan-3-yl)piperazin-1-yl]pyridin-2-yl}amino)-5-(tetra-methyl-1,3,2-dioxaborolan-2-yl)-1,2-dihydropyridin-2-one 151g (216 mg, 0.45 mmol), PdCl2(dppf) (25 mg, 0.030 mmol), K3PO4 (126 mg, 0.60 mmol), sodium acetate (49 mg, 0.60 mmol), acetonitrile (15 mL), and water (1.5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 80° C. for 2 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 1:20 methanol/dichloromethane to afford 153a as a red solid (82 mg, 41%). MS-ESI: [M+H]+ 663
