Procedure

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 313e (150 mg, 0.43 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 (170 mg, 0.43 mmol), K3PO4 (183 mg, 0.86 mmol), sodium acetate (71 mg, 0.86 mmol), Pd(dppf)Cl2 (35 mg, 0.043 mmol), acetonitrile (10 mL), and water (0.5 mL). The system was subjected to three cycles of vacuum/nitrogen flush and heated at 100° C. for 3 h. After this time the reaction was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 30:1 dichloromethane/methanol to afford 313f (131 mg, 49%) as a yellow solid. MS-ESI: [M+H]+ 625.3.
