실험 절차

A 100-mL round-bottomed flask equipped with a reflux condenser was charged with 2-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-4-chloronicotinaldehyde 103b (110 mg, 0.31 mmol), 113b (100 mg, 0.31 mmol), PdCl2(dppf) (25 mg, 0.030 mmol), K3PO4 (241 mg, 0.93 mmol), NaAcO (76 mg, 0.93 mmol), acetonitrile (15 mL), and water (0.5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 3 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified with silica-gel column chromatography eluting with 1:20 methanol/dichloromethane to afford 113c as a red solid (80 mg, 51%). MS-ESI: [M+H]+ 526.3
