Procedure

To a solution of (R)—N-(5-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxyazetidine-1-carboxamide (44 mg, 0.11 mmol) in methanol (3 mL) at ambient temperature was added sulfuric acid in methanol (531 μL, 0.11 mmol). The resulting solution was stirred for 30 minutes then concentrated to provide (R)—N-(5-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxyazetidine-1-carboxamide sulfate (38 mg, 0.074 mmol, 70% yield) as a yellow solid.
