실험 절차

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and reflux condenser was charged with 1-methyl-3-(5-(oxetan-3-yl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 163a (354 mg, 0.83 mmol), 4-chloro-2-(10-fluoro-1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)nicotinaldehyde 134c (289 mg, 0.83 mmol), PdCl2(dppf) (68 mg, 0.08 mmol), K3PO4 (352 mg, 1.66 mmol), sodium acetate (136 mg, 1.66 mmol), acetonitrile (50 mL), and water (3 mL). The system was evacuated and refilled with N2. The reaction mixture was heated at 100° C. for 2 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 30:1 dichloromethane/methanol to afford 166a (305 mg, 60%) as a brown solid. MS-ESI: [M+H]+: 613.6.
