Reaction Steps

(R)-ethyl 5-(5-(2,5-difluorophenyl)-2,2-dimethylpyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylate (136 mg, 0.340 mmol) was dissolved in MeOH (5.0 mL) and 1N NaOH (3.40 mL, 3.40 mmol) was added. The reaction was stirred at ambient temperature for 5 days and then heated at reflux for 4 hours. The reaction mixture was cooled, poured onto a mixture of brine (10 mL) and 2N HCl (5 mL) and extracted with DCM. The combined organic extracts were filtered through PS paper and concentrated to provide the title compound (123 mg, 97% yield) as a beige solid. MS (apci) m/z=373.0 (M+H).
