실험 절차

A mixture of (R)-5-(2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation B, 250 mg, 0.700 mmol) and HATU (319 mg, 0.840 mmol) in 1:1 DMF/DMSO (2 mL) was cooled to 0° C., followed first by drop-wise addition of 3-aminopropane-1,2-diol (76.5 mg, 0.840 mmol) and then addition of DIEA (366 μL, 2.10 mmol). The reaction was warmed up to ambient temperature, stirred for 20 minutes, and then directly purified on reverse phase column chromatography (Biotage SP4 system C-18 25+M cartridge, 5 to 50% acetonitrile/water), to provide the product as a white solid (295 mg, 98% yield). MS (apci) m/z=431.1 (M+H).
