Versuchsvorschrift

A 25-mL round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 297a (195 mg, 0.66 mmol), (2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}-4-(tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-yl)methyl acetate 199e (315 mg, 0.66 mmol), PdCl2(dppf) (40 mg, 0.050 mmol), K3PO4 (250 mg, 1.2 mmol), sodium acetate (100 mg, 1.20 mmol), acetonitrile (8 mL), and water (1 mL). The system was evacuated and then refilled with N2. It was then heated at 100° C. for 1 h. The mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with 20:1 dichloromethane/methanol to afford 297b as a yellow solid (150 mg, 38%). MS-ESI: [M+H]+ 612.3.
