실험 절차

A round-bottomed flask equipped with a reflux condenser was charged with 231c (200 mg, 0.50 mmol), (S)-6-chloro-2-methyl-4-(5-(2-methyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)pyridazin-3(2H)-one 224c (195 mg, 0.50 mmol), PdCl2(dppf) (24 mg, 0.030 mmol), K3PO4 (212 mg, 1.0 mmol), sodium acetate (98 mg, 1.0 mmol), acetonitrile (30 mL), and water (3 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 2 h. It was then cooled to room temperature and filtered. The filtrate was evaporated under reduced pressure. The residue was purified with silica-gel column chromatography eluting with 1:3 petroleum/ethyl acetate to afford 231d as a yellow solid (213 mg, 60%). MS-ESI: [M+H]+ 712.3
