A sealed tube equipped with a magnetic stirrer was charged with 3-bromo-5-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyri-dine-4-carbaldehyde 107f (100 mg, 0.26 mmol), 328a (110 mg, 0.26 mmol), Pd(dppf)Cl2 (10 mg, 0.026 mmol), sodium acetate (50 mg, 0.50 mmol), K3PO4 (100 mg, 0.50 mmol), and acetonitrile/water (5 mL/1 mL). After three cycles of vacuum/nitrogen flush, the mixture was heated at 100° C. for 2 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 10:1 dichloromethane/methanol to afford 328b (50 mg, 32%) as a brown solid. MS-ESI: [M+H]+ 611.3.
