実験手順

A round-bottomed flask was charged with 139a (100 mg, 0.30 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 101 l (140 mg, 0.30 mmol), PdCl2(dppf) (25 mg, 0.03 mmol), K3PO4.3H2O (160 mg, 0.60 mmol), NaOAc (59 mg, 0.60 mmol), acetonitrile (10 mL), and H2O (5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 3 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified on flash column chromatography eluting with 1:3 petroleum/ethyl acetate to afford 139b as a yellow solid (95 mg, 50%). LCMS: [M+H]+ 635
