Procedure

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 326b (160 mg, 0.46 mmol), {3-[(acetoxy)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 (300 mg, 0.69 mmol), K3PO4 (195 mg, 0.92 mmol), sodium acetate (75 mg, 0.92 mmol), 1,1′-bis(diphenylphosphino) ferrocenedichloropalladium(II) (42 mg, 0.046 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 gel-silica column chromatography eluting with 60:1 dichloromethane/methanol to afford 326c (130 mg, 45%) as a black solid. MS-ESI: [M+H]+ 621.3
