Procedure
A mixture of 109e (400 mg, 1.0 mmol), 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 (490 mg, 1.0 mmol), PdCl2(dppf) (80 mg, 0.1 mmol), 2.0 M Na2CO3 (2.0 equiv) in DMF (4 mL) was heated at 100° C. for 2 h. Brine was added and the mixture was extracted with EA (50 mL) three times. The combined organic layer was concentrated under reduced pressure. The residue was purified by flash column chromatography eluting with 30:1 DCM/MeOH to afford 109f as a brown solid (354 mg, 52%). LCMS: [M+H]+ 668
