実験手順

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with {3-[(acetyloxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatri-cyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (595 mg, 1.5 mmol), 290a (282 mg, 1.0 mmol), K3PO4 (424 mg, 2.0 mmol), sodium acetate (164 mg, 2.0 mmol), 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (82 mg, 0.1 mmol), and acetonitrile/water (15/1 mL). After three cycles of vacuum/N2 flush, the mixture was heated at 100° C. for 1.5 h. The mixture was cooled to room temperature and concentrated under reduced pressure. The residue was partitioned between dichloromethane (30 mL) and water (30 mL). The aqueous layer was extracted with dichloromethane (3×20 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 50/1) to 290b (300 mg, 54%) as yellow solid. MS-ESI: [M+H]+ 556.1
