実験手順

A sealed tube was charged with the mixture of 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 210d (420 mg, 0.9 mmol), 328c (300 mg, 0.78 mmol), Pd(dppf)Cl2 (66 mg, 0.078 mmol), K3PO4.3H2O(360 mg, 1.56 mmol), and NaOAc (130 mg, 1.56 mmol) in CH3CN(20 ml). The system was evacuated and then refilled with N2. And the reaction mixture was heated at 110° C. for 2 h. Then, the mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by flash column chromatography eluting with 30:1 methylene chloride/methanol to afford 328d as a yellow solid (400 mg, 72%). MS: [M+H]+ 696.
