Reaction Steps

To a DCM (5 mL) solution of (R)-5-(2-(5-fluoro-2-methoxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-amine (25 mg, 0.076 mmol) and DIEA (0.04 mL, 0.23 mmol) was added CDI (25 mg, 0.15 mmol) at ambient temperature in one portion. After stirring for one hour, (S)-pyrrolidin-3-ol (20 mg, 0.23 mmol) was added in one portion. The reaction was stirred overnight before it was concentrated and directly purified by reverse-phase column chromatography, eluting with 0 to 60% acetonitrile/water to yield the final product as a yellowish solid (28 mg, 83% yield). MS (apci) m/z=441.2 (M+H).
