To a 20 mL scintillation vial was charged tert-butyl 4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)-amino)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)piperidine-1-carboxylate (80 μmol, 56 mg) followed by ethanol (2 mL) and H2O (500 μL). To this solution was added 2 mL of 4N HCl in 1,4-dioxane. This solution was heated to 60° C. for 2 hours. Upon completion, the reaction mixture was diluted with DCM (10 mL) and washed with NaHCO3(aq) and extracted with DCM twice more. The combined organics were then dried over Na2SO4 and the solvent was removed in vacuo to yield 5-(piperidin-4-yl)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-7-amine (20.3 mg, 59 umol) as cream-colored solid
