실험 절차

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 117f (607 mg, 1.0 mmol), 4-fluoro-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl acetate 101k (482 mg, 1.0 mmol), Pd(dppf)Cl2 (82 mg, 0.10 mmol), K3PO4 (424 mg, 2.0 mmol), sodium acetate (164 mg, 2.0 mmol), water (0.5 mL), and acetonitrile (20 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 30:1 dichloromethane/methanol to afford 117g as yellow solid (600 mg, 72%). MS-ESI: [M+H]+ 836.5
