Versuchsvorschrift

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 155c (367 mg, 1.1 mmol), 3-(acetoxymethyl)-2-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)pyridine-4-ylboronic acid 116c (908.6 mg, 2.2 mmol), Pd2(dba)3 (100.6 mg, 0.11 mmol), P(cy)3 (122.8 mg, 0.44 mmol), Cs2CO3 (717 mg, 2.2 mmol), dioxane (20 mL), and water (0.5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 110° 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 35:1 dichloromethane/methanol to afford 155d (120 mg, 16%) as a yellow solid. MS-ESI: [M+H]+ 669.8
