Procedure

To (R)-tert-butyl 3-(5-(2-(2-chloro-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-ylcarbamoyl)azetidine-1-carboxylate (Example 46; 17 mg, 0.033 mmol), was added 0.5 mL 50% TFA solution in DCM and stirred at ambient temperature for 10 minutes. The reaction was concentrated, treated with ether, and filtered, giving the final product (TFA salt) as a fine beige powder (12 mg, 88% yield). MS (apci) m/z=415.2 (M+H).
