Versuchsvorschrift
A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 4-chloro-2-{4,4-dimethyl-9-oxo-1,10-diaza-tricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridine-3-carbaldehyde 108a (350 mg, 1.02 mmol), 1-methyl-3-(5-(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 1011(476 mg, 1.02 mmol), Pd(dppf)Cl2 (83 mg, 0.10 mmol), K3PO4 (526 mg, 3.06 mmol), and tetrahydrofuran (20 mL). After three cycles of vacuum/argon flush, the mixture was heated at reflux for 4 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 dichloromethane/methanol (40:1) to afford 108b as white solid (400 mg, 61%). MS: [M+H]+ 649.4.
