Procedure

tert-Butyl 4-(7-amino-6-bromo-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)piperazine-1-carboxylate (0.09 mmol) was charged to a 20 mL scintillation vial. To this vial was added 4N HCl in 1,4-dioxane. The reaction mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated in vacuo and 6-chloro-5-(piperazin-1-yl)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-7-amine was used without further purification.
