実験手順

A 100-mL round-bottomed flask equipped with a reflux condenser was charged with 4-chloro-2-(1-oxo-6,7,8,9-tetrahydropyridazino[4,5-b]indolizin-2(1H)-yl)nicotinaldehyde 193f (200 mg, 0.60 mmol), 1-methyl-3-(5-methyl-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 135a (230 mg, 0.60 mmol), sodium acetate (100 mg, 1.2 mmol), K3PO4 (320 mg, 1.2 mmol), PdCl2(dppf) (50 mg, 0.060 mmol), acetonitrile (25 mL), and water (1 mL). After bubbling nitrogen through the resulting mixture for 30 minutes, the mixture was heated at 100° C. for 3 hours. The reaction mixture was cooled to room temperature and concentrated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 20:1 methylene chloride/methanol to afford 204a (185 mg, 55%) as a brown solid. MS-ESI: [M+H]+ 552.3.
