Procedure

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 321a (140 mg, 0.37 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 (355 mg, 0.74 mmol), K3PO4 (157 mg, 0.74 mmol), sodium acetate (61 mg, 0.74 mmol), 1,1′-bis(diphenylphosphino) ferrocenedichloropalladium(II) (36 mg, 0.040 mmol), acetonitrile (10 mL), and water (0.2 mL). The system was subjected to three cycles of vacuum/nitrogen flush and heated at 100° C. under N2 protection for 1.5 h. Analysis of reaction mixture by LCMS showed complete conversion to the desired product. The reaction 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 separated and 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 gel-silica column chromatograph the by eluting with 60:1 dichloromethane/methanol to afford 320b (105 mg, 41%) as a black solid. MS-ESI: [M+H]+ 695.3
