実験手順

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 3-(5-acetyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)-5-bromo-1-methylpyridin-2(1H)-one 209c (185 mg, 0.50 mmol), {3-[(acetyloxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (200 mg, 0.50 mmol), Pd(dppf)Cl2 (41 mg, 0.050 mmol), sodium acetate (82 mg, 1.0 mmol), K3PO4 (212 mg, 1.0 mmol), water (0.5 mL), and acetonitrile (10 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 2 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica-gel column chromatography eluting with 25:1 dichloromethane/methanol to afford 212a (180 mg, 56%) as a yellow solid. MS-ESI: [M+H]+ 639.3
