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)
