To a solution of 5-bromo-1-methyl-3-(5-(oxetan-3-yl)-4,5,6,7-tetrahydro-pyrazolo[1,5-a]pyrazin-2-ylamino)pyridin-2(1H)-one 252a (1 g, 2.64 mmol), 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(1,3,2-dioxaborolane) (2 g, 7.92 mmol) in dioxane (40 mL) was added PdCl2(dppf) (215 mg, 0.26 mmol) and CH3COOK (776 mg, 7.92 mmol). The mixture was stirred at 100° C. for 6 h under argon atmosphere. After reaction the mixture was filtered and evaporated in vacuo. The residue was purified by reverse phase combiflash eluting with 0.3% NH4HCO3 in 1:3 water/CH3CN to give 143a as a white solid (300 mg, 33%). MS: (M+H)+ 346.
