Participants

Reaction Steps

To a DMF (1.0 mL) solution of (R)-5-(2-(5-fluoropyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation I, 85 mg, 0.26 mmol) was added HATU (118 mg, 0.31 mmol) and 3-methylazetidin-3-ol 2,2,2-trifluoroacetate (63 mg, 0.31 mmol) at ambient temperature, followed by addition of DIEA (0.14 mL, 0.78 mmol) at 0° C. After stirring for 5 minutes at ambient temperature, the reaction was directly purified by reverse-phase chromatography (5 to 45% acetonitrile/water) to yield the final product as white solid (84 mg, 82%). LCMS (apci) m/z=397.1 (M+H).
