실험 절차

To a DCM (1 mL) solution of (R)-5-(2-(5-fluoropyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-amine (25 mg, 0.084 mmol) was added CDI (27 mg, 0.17 mmol) at ambient temperature in one portion. After stirring for two hours, (S)-pyrrolidin-3-ol (15 mg, 0.17 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 40% acetonitrile/water to yield the final product as a solid (27 mg, 78% yield). MS (apci) m/z=412.2 (M+H).
