実験手順

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 139e (177 mg, 0.50 mmol), 3-(acetoxymethyl)-2-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)pyridin-4-ylboronic acid 116c (207 mg, 0.50 mmol), Pd(dppf)Cl2 (41 mg, 0.050 mmol), sodium acetate (82 mg, 1.0 mmol), K3PO4.trihydrate (266 mg, 1.0 mmol), water (6 drops), and acetonitrile (5 mL). After three cycles of vacuum/argon 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 50:1 dichloromethane/methanol to afford 139f (161 mg, 50%) as a brown solid. MS-ESI: [M+H]+ 642.3
