Versuchsvorschrift
A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 324b (40 mg, 0.11 mmol), (2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-yl)methyl acetate 199e (105 mg, 0.22 mmol), K3PO4 (47 mg, 0.22 mmol), sodium acetate (18 mg, 0.22 mmol), 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (20 mg, 0.022 mmol), acetonitrile (10 mL), and water (6 drops). The system was subjected to three cycles of vacuum/nitrogen flush and heated at 100° C. under N2 protection for 1.5 h. LCMS analysis showed complete conversion to the desired product. The reaction mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was diluted with dichloromethane (50 mL) and water (50 mL). The aqueous layer was separated and extracted with dichloromethane (3×20 mL). The combined extract was dried over Na2SO4, filtered, and concentrated under reduced pressure. The dark residue was purified by silica-gel column chromatography eluting with 60:1 dichloromethane/methanol to afford 324c (40 mg, 52%) as a black solid. MS-ESI: [M+H]+ 695.3
