Procedure

To (R)-tert-butyl 4-(5-(2-(2-chloro-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-ylcarbamoyl)-4-methylpiperidine-1-carboxylate (Example 48; 28 mg, 0.05 mmol), was added 1 mL 4 N HCl solution in dioxane and stirred at ambient temperature for 10 minutes. The reaction was concentrated, treated with ether, and filtered, giving the final product (HCl salt) as a fine beige powder. MS (apci) m/z=457.1 (M+H).
