実験手順

A sealed tube was charged with 117d (100 mg, 0.28 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 (115 mg, 0.3 mmol), PdCl2(dppf) (25 mg, 0.03 mmol), K3PO4 (126 mg, 0.6 mmol), and NaOAc (60 mg, 0.6 mmol) in MeCN (8 mL) and H2O (1 mL). The system was evacuated and refilled with N2. The reaction mixture was heated 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 flash column eluting with DCM:MeOH (20:1) to afford 117e (100 mg, 40%). MS: [M+H]+ 617.
