Versuchsvorschrift

A suspension of 135a (385 mg, 1 mmol), 4-chloro-2-(10-fluoro-1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)nicotinaldehyde 134c (347 mg, 1 mmol), K3PO4 (424 mg, 2 mmol), NaOAc (164g, 2 mmol) and 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (41 mg, 0.05 mmol) in CH3CN (50 ml) was heated at 100° C. under an N2 balloon for 4h. Analysis of reaction mixture by LCMS showed completed conversion to the desired product. The reaction mixture was cooled to room temperature and diluted with DCM (50 ml) and water (80 mL). The aqueous layer was separated and extracted with DCM (3×50 mL). The combined organic layer was dried over Na2SO4, filtered, and concentrated. The dark residue was purified by silica gel column chromatography eluting with DCM/MeOH (from 80/1 to 30/1) to afford 135b (285 g, 50%) as yellow solid. MS: [M+H]+ 571
