Procedure

A 25-mL round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 302d (200 mg, 0.52 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 (210 mg, 0.53 mmol), PdCl2(dppf) (37 mg, 0.050 mmol), K3PO4 (250 mg, 1.2 mmol), sodium acetate (100 mg, 1.20 mmol), acetonitrile (8 mL), and water (0.5 mL). The system was evacuated and then refilled with N2. The mixture was heated at 100° C. for 1 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with 20:1 dichloromethane/methanol to afford 302e as a yellow solid (150 mg, 44%). MS-ESI: [M+H]+ 655.3.
