Reaction Steps
To a DMF (0.25 mL) solution of (R)-5-(2-(5-fluoropyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation I, 25 mg, 0.076 mmol) and HATU (35 mg, 0.092 mmol) was added 5-fluoropyridin-2-amine (10 mg, 0.092 mmol), followed by drop-wise addition of DIEA (0.040 mL, 0.23 mmol) at ambient temperature. The reaction was heated at 70° C. overnight, cooled, and directly purified by reverse-phase chromatography (5 to 66% acetonitrile/water) to yield the final product as white solid (25 mg, 78%). LCMS (apci) m/z=422.0 (M+H).
