Reaction Steps
A 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 (105 mg, 0.26 mmol), 135c (100 mg, 0.28 mmol), PdCl2(dppf) (29 mg, 0.039 mmol), K3PO4 (100 mg), and NaOAc (50 mg) in MeCN (10 mL) and water (3 mL) was heated at 110° C. for 2 h. The solvent was evaporated in vacuo. The residue was purified on reverse phase Combi-flash to give 135d (100 mg, 60%). MS: [M+H]+ 640.
