실험 절차

A 100-mL round-bottomed flask equipped with a reflux condenser was charged with 170b (150 mg, 0.44 mmol), 1-methyl-3-(5-methyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)-5-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 135a (169 mg, 0.44 mmol), sodium acetate (72 mg, 0.88 mmol), K3PO4 (234 mg, 0.88 mmol), Pd (dppf) Cl2 (36 mg, 0.044 mmol), acetonitrile (20 mL), and water (1 mL). After bubbling nitrogen through the reaction mixture for 30 minutes, it was heated at 100° C. for 3 hours. The reaction mixture was evaporated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with 25:1 dichloromethane/methanol to afford 170c (146 mg, 52%) as a brown solid. MS-ESI: [M+H]+ 565.3
