Procedure

(R)-methyl 1-(5-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-ylcarbamoyl)cyclopropanecarboxylate (Example 33; 24 mg, 0.054 mmol), was dissolved in a mixture solvent of THF/MeOH/water (0.3/0.3/0.2 mL), followed by addition of lithium hydroxide monohydrate (6 mg, 0.14 mmol). After stirring at ambient temperature for five hours, the reaction mixture was diluted with water (15 mL), acidified with 1N HCl (aq.) to pH ˜3, and filtered, giving the final product as a fine white solid (19 mg, 82% yield). MS (apci) m/z=428.2 (M+H).
