Procedure

To a DMF (0.4 mL) solution of (R)-5-(2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation K, 30 mg, 0.084 mmol) was added HATU (38 mg, 0.10 mmol) and azetidin-3-ol hydrochloride (11 mg, 0.10 mmol) at ambient temperature, followed by dropwise addition of DIEA (0.044 ml, 0.25 mmol) at 0° C. After stirring for 20 minutes at ambient temperature, the reaction was directly purified by reverse-phase chromatography (5 to 50% acetonitrile/water) to yield the final product as white solid (26 mg, 75%). LCMS (apci) m/z=413.1 (M+H).
