Versuchsvorschrift

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 203b (178 mg, 0.50 mmol), {3-[(acetyloxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (200 mg, 0.50 mmol), K3PO4 (212 mg, 1.0 mmol), sodium acetate (82 mg, 1.0 mmol), 1,1′-bis(diphenylphosphino)ferrocene-dichloropalladium(II) (21 mg, 0.025 mmol), acetonitrile (10 mL), and water (0.5 mL). After bubbling nitrogen through the mixture for 30 minutes, it was heated at 100° C. under N2 protection for 1 h. Analysis of reaction mixture by LCMS showed complete conversion to the desired product. The reaction mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the residue was diluted with dichloromethane (20 mL) and water (10 mL). The aqueous layer was separated and extracted with dichloromethane (2×20 mL). The combined organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure. The dark residue was purified by silica-gel column chromatography eluting with dichloromethane/methanol (80/1 to 30/1) to afford 203c (135 mg, 43%) as yellow solid. MS-ESI: [M+H]+ 584
