Reaction Steps
A mixture of 140a (595 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 (882 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. After reaction CH3CN was evaporated and the residue was purified by reverse phase Combi-flash eluting with 0.3% NH4HCO3 in 1:4 water/CH3CN to give 140b as a brown solid (477 mg, 44%). LCMS: [M+H]+572.
