実験手順

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 5-bromo-3-(5-ethyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)-1-methylpyridin-2(1H)-one 208c (300 mg, 0.85 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 (1.21 g, 3.16 mmol), PdCl2(dppf) (35 mg, 0.043 mmol), K3PO4 (361 mg, 1.70 mmol), sodium acetate (140 mg, 1.70 mmol), acetonitrile (10 mL), and water (0.5 mL). The system was evacuated and refilled with N2. The reaction mixture was stirred at 100° C. 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 30:1 dichloromethane/methanol to afford 177a (365 mg, 60%) as a brown oil. MS-ESI: [M+H]+ 611
