実験手順

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 152e (300 mg, 0.67 mmol), 3-(acetoxymethyl)-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)pyridin-4-ylboronic acid 113h (257 mg, 0.67 mmol), Pd(dppf)Cl2 (55 mg, 0.067 mmol), K3PO4 (284 mg, 1.34 mmol), sodium acetate (110 mg, 1.34 mmol), water (6 drops), and acetonitrile (20 mL). After three cycles of vacuum/argon flush, the mixture was stirred at reflux for 3 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 152f as a brown solid (200 mg, 42%). MS-ESI: [M+H]+ 705.4.
