Procedure

A 50-mL round bottomed flask equipped with a reflux condenser was charged with 340e (180 mg, 0.412 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 (327.3 mg, 0.824 mmol), Pd(dppf)Cl2 (16.8 mg, 0.0206 mmol), K3PO4 (174.7 mg, 0.824 mmol), sodium acetate (67.6 mg, 0.824 mmol), acetonitrile (10 mL), and water (3 drops). The system was subjected to three cycles of vacuum/nitrogen flush and heated at 100° C. under N2 protection for 1 h. Analysis of the reaction mixture by LCMS showed complete conversion to the desired product. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 20:1 dichloromethane/methanol to afford 340f as a yellow oil (190 mg, 65%). MS-ESI: [M+H]+ 709.4
