반응 단계
To a mixture of (R)-5-(2-(2-chloro-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-amine (Example 8, Step A; 25 mg, 0.075 mmol), 1-(tert-butoxycarbonyl)-4-methylpiperidine-4-carboxylic acid (22 mg, 0.090 mmol), and HATU (34 mg, 0.090 mmol) was added 0.6 mL DMF to make a solution. After cooling in an ice bath for 10 minutes, DIEA (0.039 mL, 0.23 mmol) was added to the reaction dropwise. The reaction was allowed to warm up to ambient temperature and stirred overnight. The reaction mixture was directly purified by reverse-phase column chromatography, eluting with 5 to 80% acetonitrile/water to yield the final product as a yellowish powder (28 mg, 67% yield). MS (apci) m/z=557.1 (M+H).
