Procedure

To a solution of (R)—N-(5-(2-(2-chloro-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxyazetidine-1-carboxamide (11.1 mg, 0.0258 mmol) in methanol (1 mL) at ambient temperature was added sulfuric acid in methanol (258 μL, 0.0258 mmol). The resulting solution was stirred for 30 minutes then concentrated to provide (R)—N-(5-(2-(2-chloro-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxyazetidine-1-carboxamide sulfate (10 mg, 0.0189 mmol, 73.4% yield) as a yellow solid.
