実験手順

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 6-methoxypyridazin-3-amine (65 mg, 0.52 mmol), XantPhos (29 mg, 0.050 mmol), Pd2dba3 (45 mg, 0.050 mmol), [4-(5-bromo-1-methyl-6-oxo-1,6-dihydropyridin-3-yl)-2-{4,4-dimethyl-9-oxo-1,10-diazatricy-clo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-3-yl]methyl acetate 273a (281 mg, 0.52 mmol), Cs2CO3 (326 mg, 1.0 mmol), and 1,4-dioxane (10 mL). After bubbling nitrogen through the resulting mixture for 20 minutes, it was heated at reflux for 2 h. After the completion of the reaction, the mixture was evaporated under reduced pressure and the residue was partitioned between ethyl acetate (20 mL) and water (10 mL). The ethyl acetate was concentrated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with 20:1 dichloromethane/methanol to afford 306a (180 mg, 60%). MS-ESI: [M+H]+ 584.3.
