실험 절차

To a mixture of (R)-5-(2-(3-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-amine (Example 6, Step A; 40 mg, 0.13 mmol, prepared as described in a previous example), 1-methyl-1H-imidazole-2-carboxylic acid (34 mg, 0.27 mmol), and HATU (102 mg, 0.27 mmol) was added 1.0 mL DMF to make a solution. After cooling in an ice bath for 10 minutes, DIEA (0.07 mL, 0.4 mmol) was added to the reaction drop-wise. The reaction was allowed to warm up to ambient temperature and stirred for 10 minutes. The reaction mixture was diluted with EtOAc (15 mL), washed with water and brine (5 mL each), concentrated, and purified by reverse-phase column chromatography, eluting with 5 to 65% acetonitrile/water to yield the final product as a yellowish solid (37 mg, 68% yield). MS (apci) m/z=406.2 (M+H).
