Procedure

To a mixture of (R)-5-(2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation K, 200 mg, 0.560 mmol) and HATU (255 mg, 0.672 mmol) in DMF (2 mL) was added DIEA (292 μL, 1.68 mmol), followed by dropwise addition of tert-butyl 3-aminopropylcarbamate (117 mg, 0.672 mmol) at ambient temperature. After stirring for 3 hours, the reaction was directly purified by reverse-phase chromatography (5 to 70% acetonitrile/water) to yield the final product as white solid (250 mg, 87%). LCMS (apci) m/z=414.1 (M+H-Boc).
