Reaction Steps

Potassium carbonate (98 mg, 0.71 mmol) was added to a solution of N-[1-[2-(4-aminopiperidin-1-yl)ethyl]-3-[5-chloro-2-(difluoromethoxy)phenyl]-1H-pyrazol-4-yl]pyrazolo[1,5-a]pyrimidine-3-carboxamide (290 mg, 0.55 mmol) and tert-butyl 2-bromoacetate (96 mg, 0.49 mmol) in DMF (5 mL). The resulting mixture was stirred at 50° C. overnight. The resulting mixture was concentrated under vacuum. The residue was purified by flash chromatography on silica eluting with 15% MeOH in DCM to afford 150 mg (43%) of tert-butyl 2-[[1-(2-[3-[5-chloro-2-(difluoromethoxy)phenyl]-4-[pyrazolo[1,5-a]pyrimidine-3-amido]-1H-pyrazol-1-yl]ethyl)piperidin-4-yl]amino]-acetate as a yellow solid. LCMS (Method 24) [M+H]+=645.2, RT=1.39 min.
