Procedure

A 15 mL microwave reaction vial with a magnetic stirrer was charged with 205b (0.35 g, 1 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 210d (0.48 g, 1 mmol), potassium phosphate (0.54 g, 2 mmol), sodium acetate (0.17 g, 2 mmol), acetonitrile (10 mL), water (1 mL), and 1,1′-bis(diphenylphosphino)ferrocene-palladium(II) dichloride dichloromethane (0.08 g, 0.1 mmol). The mixture was heated at 110° C. for 2 hours under argon atmosphere. After this time, the mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the residue was purified by column-chromatography eluting with 40:1 DMC/methanol to give 205c (0.22 g, 36%). LC/MS: m/z 625 (M+H)+
