실험 절차

A round-bottomed flask was charged with 2-bromo-4-fluoro-6-(1-oxo-6,7,8,9-tetrahydropyrazino[1,2-a]indol-2(1H)-yl)benzaldehyde 121f (159 mg, 0.41 mmol), 122a (213 mg, 0.43 mmol), PdCl2(dppf) (29 mg, 0.04 mmol), K3PO4 (182 mg, 0.86 mmol), sodium acetate (71 mg, 0.86 mmol), acetonitrile (15 mL), and water (1.5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 80° C. for 3 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 1:20 methanol/dichloromethane to afford 122b as a red solid (120 mg, 43%). MS: [M+H]+ 678.3
