Versuchsvorschrift

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 2-bromo-6-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-4-fluorobenzaldehyde 102h (168 mg, 0.40 mmol), 111f (198 mg, 0.40 mmol), Pd(dppf)Cl2 (15 mg, 0.02 mmol), K3PO4 (170 mg, 0.8 mmol), sodium acetate (66 mg, 0.8 mmol), acetonitrile (5 mL), and water (0.8 mL). After three cycles of vacuum/argon flush, the mixture was heated at reflux for 2 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 30:1 dichloromethane/methanol to afford 111g as a white solid (100 mg, 35%). MS: [M+H]+ 710.3
