Versuchsvorschrift

A mixture of (R)-5-(2-(5-fluoro-2-methoxy pyridin-3-yl)pyrrolidin-1-yl)-N-(3-hydroxypropyl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (20 mg, 0.0483 mmol) in HCl (4 N dioxane, 1.2 mL, 4.83 mmol) was heated at 85° C. overnight. The reaction mixture was concentrated, triturated with ether, and filtered, to provide the crude product as a beige solid, which was directly used in the next step without further purification (22 mg, 106% yield). MS (apci) m/z=419.1 (M+H).
