実験手順

A sealed tube equipped with a magnetic stirrer was charged with 6-chloro-2-methyl-4-({5-[(morpholin-4-yl)carbonyl]pyridin-2-yl}amino)-2,3-dihydropyridazin-3-one 226a (244 mg, 0.70 mmol), 3-(acetoxymethyl)-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)pyridin-4-ylboronic acid 113i (558 mg, 1.5 mmol), Pd2(dba)3 (64 mg, 0.070 mmol), tricyclohexylphospine (39 mg, 0.14 mmol), cesium carbonate (456 mg, 1.4 mmol), 1,4-dioxane (7 mL), and water (6 drops). After three cycles of vacuum/argon flush, the mixture was stirred at 110° C. for 4 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica-gel column chromatography eluting with 40:1 ethyl acetate/methanol to afford 227a as a yellow solid (290 mg, 63%). MS-ESI: [M+H]+ 653.3
