Participants

Reaction Steps

To a solution of (R)—N-(5-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-yl)-3-hydroxy-3-methylazetidine-1-carboxamide (3.1 mg, 0.0072 mmol) in methanol (1 mL) at ambient temperature was added sulfuric acid in methanol (145 μL, 0.014 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-hydroxy-3-methylazetidine-1-carboxamide sulfate (3.3 mg, 0.0063 mmol, 87% yield) as a yellow solid.
