Reaction Steps
To the reaction flask, 3-((7-chloropyrazolo[1,5-a]pyrimidin-5-yl)methyl)benzonitrile (400 mg, 1.5 mmol) was added along with cyclopropylamine (115 μL, 1.6 mmol), triethylamine (230 μL, 1.6 mmol), and acetonitrile (3 mL). The reaction was stirred at room temperature for 8 hours at 80° C. then cooled to room temperature, diluted with water, filtered and washed with water. The product, 3-((7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidin-5-yl)methyl)benzonitrile, was collected as a solid in 83% yield after drying under vacuum overnight. LCMS (M+1=290)
