Versuchsvorschrift

A flask was charged with 4-chloro-2-(1-oxo-6,7,8,9-tetrahydropyrazino[1,2-a]indol-2(1H)-yl)nicotinaldehyde 103b (88 mg, 0.27 mmol), 1-methyl-3-(5-(4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 101l (125 mg, 0.27 mmol), PdCl2(dppf) (18 mg, 0.02 mmol), K3PO4 (30 mg), in THF (5 mL) and H2O (1 mL). The system was evacuated and refilled with N2. The reaction mixture was refluxed for 4 h, and then cooled to room temperature. It was then filtered and the filtrate was concentrated under reduced pressure. The resulting residue was purified by flash column chromatography eluting with 10:1 of DCM/MeOH to afford 121a (90 mg, 56%) as a yellow solid. MS: [M+H]+ 633.
