Procedure

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 329a (100 mg, 0.30 mmol), 3-(5-(2-methoxyethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)-1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 328a (257 mg, 0.60 mmol), Pd(dppf)Cl2 (25 mg, 0.030 mmol), K3PO4 (127 mg, 0.60 mmol), sodium acetate (49 mg, 0.60 mmol), water (0.50 mL), and THF (10 mL). After three cycles of vacuum/nitrogen flush, the mixture was heated at reflux for 1 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 30:1 dichloromethane/methanol to afford 329b as a brown solid (60 mg, 34%). MS-ESI: [M+H]+ 611.3.
