1,1'-Carbonyldiimidazole → 5-((4-(7-amino-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)methyl)-1,3,4-oxadiazol-2(3H)-one

Reaction Steps

To a 20 mL scintillation vial was charged 2-(4-(7-amino-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetohydrazide (0.12 mmol), THF (5 mL), and 1,1′-carbonyldiimidazole (0.12 mmol, 25 mg). The resulting solution was stirred at room temperature for 2 hours. After 2 hours, the solvent was removed in vacuo and the residue taken up in 3:1 DMSO:MeCN. The solids are removed via centrifugation, and the title compound was purified via reverse-phase HPLC.
