실험 절차

To a DCM (0.7 mL) solution of (R)-5-(4,4-difluoro-2-(3-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-amine (25 mg, 0.074 mmol), was added CDI (18 mg, 0.11 mmol) at ambient temperature in one portion. After stirring two hours, azetidin-3-ol hydrochloride (16 mg, 0.15 mmol) was added in one portion, followed by addition of DIEA (0.039 mL, 0.22 mmol). The reaction was stirred overnight, then concentrated, and the residue was directly purified by reverse-phase column chromatography, eluting with 0 to 45% acetonitrile/water to yield the final product as a yellowish oil (15 mg, 48% yield). MS (apci) m/z=433.1 (M+H).
