Reaction Steps
A mixture of 206f (800 mg, 1.9 mmol), 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 (114a) (873 mg, 1.9 mmol), CH3COONa (309 mg, 3.8 mmol), PdCl2(dppf) (153 mg, 0.19 mmol) and K3PO4 (1 g, 3.8 mmol) suspended in CH3CN (30 mL) and H2O (2 mL) was heated at 110° C. for 15 h under argon atmosphere. It was then evaporated and the residue was purified by reverse phase Combi-flash eluting with 0.3% NH4HCO3 in 1:4 water/CH3CN to give 206g as a brown solid (800 mg, 63%). MS: (M+H)+ 684
