실험 절차

To a DCM (0.8 mL) solution of (R)-5-(2-(2-chloro-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-amine (30 mg, 0.090 mmol) was added CDI (29 mg, 0.18 mmol) at ambient temperature in one portion. After stirring two hours, azetidin-3-ol hydrochloride (20 mg, 0.18 mmol) was added in one portion, followed by addition of DIEA (0.047 mL, 0.27 mmol). The reaction was stirred for 5 minutes before it was concentrated and directly purified by reverse-phase column chromatography, eluting with 5 to 50% acetonitrile/water to yield the final product as a yellowish foamy powder (33 mg, 85% yield). MS (apci) m/z=431.1 (M+H).
