Reaktionsschritte

To the reaction flask, 5,7-dichloropyrazolo[1,5-a]pyrimidine (3 g, 16 mmol) was added along with ammonium hydroxide solution (48 mL). The heterogeneous reaction was refluxed at 85° C. for 12 hours. After cooling to room temperature, the mixture was filtered, washed with water, and dried under vacuum overnight. The product, 5-chloropyrazolo[1,5-a]pyrimidin-7-amine, was collected as an off-white solid in 88% yield. LCMS (M+1=169)
