실험 절차

To a DCM (0.6 mL) solution of (R)-5-(2-(3-chloro-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-amine (Example 11, Step A; 20 mg, 0.06 mmol), was added CDI (20 mg, 0.12 mmol) at ambient temperature in one portion. After stirring two hours, (S)-pyrrolidin-3-ol (16 mg, 0.18 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 solid (50 mg, 83% yield). MS (apci) m/z=445.2 (M+H).
