Procedure

To a mixture of tert-butyl 3-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-6-(1-ethoxyvinyl)-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)-8-azabicyclo[3.2.1]octane-8-carboxylate (1.1 g, 1.3 mmol) in dioxane (7 mL) was added 4 M HCl in water (2.6 ml) at 0° C. After stirring for 10 min at 0° C., 4 M HCl in dioxane (2.6 mL) was added. The reaction mixture was stirred at 0° C. for 30 min and the cooling bath was removed to warm it up to room temperature for 15 h, at which time LC/MS analysis confirmed full consumption of starting material. The solvent was removed in vacuo to get the desired product as an HCl salt.
