실험 절차

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with (S)-5-bromo-1-methyl-3-(5-(2-methyl-4-(oxetan-3-yl)piperazin-1-yl)pyrazin-2-ylamino)pyridin-2(1H)-one (90 mg, 0.21 mmol) 191i, 3-(acetoxymethyl)-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)pyridin-4-ylboronic acid 113i (80.4 mg, 0.21 mmol), Pd(dppf)Cl2 (17.2 mg, 0.021 mmol), K3PO4 (89 mg, 0.42 mmol), sodium acetate (57.1 mg, 0.42 mmol), water (0.5 mL), and acetonitrile (30 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 dichloromethane/methanol (50:1 to 30:1) to afford 228a as brown solid (60 mg, 42%). MS-ESI: [M+H]+ 694.3.
