Versuchsvorschrift

A 50-mL flask equipped with a reflux condenser was charged with 4-chloro-2-(1-oxo-6,7,8,9-tetrahydropyrazino[1,2-a]indol-2(1H)-yl)nicotinaldehyde 103b (164 mg, 0.50 mmol), (S)-3-(5-(2-ethyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)-1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 161f (347 mg, 0.70 mmol), potassium acetate (137 mg, 1.4 mmol), 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (29 mg, 0.035 mmol), water (5 drops), and acetonitrile (20 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. under argon atmosphere for 3 h. The reaction mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was diluted with dichloromethane (50 mL) and water (50 mL). The aqueous layer was separated and extracted with dichloromethane (3×20 mL). The combined organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure. The dark residue was purified by silica-gel column chromatography eluting with dichloromethane/methanol (80/1 to 25/1) to afford 165a (151 mg, 46%) as yellow solid. MS-ESI: [M+H]+ 661
