反应详情

6-Bromomethyl-7-(2,2-dimethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile (3 mmol) and 3-nitro-[1,2,4]triazole (3 mmol) are dissolved in DMSO (20 ml). Potassium carbonate (6 mmol) is added to the solution. The mixture is allowed to stir at room temperature overnight. The reaction mixture is diluted with H2O and extracted with AcOEt. The organic layer is dried over MgSO4 and evaporated in vacuo. The residue is purified by silica gel column chromatography (n-hexane:AcOEt=1:5) to give 7-(2,2-dimethyl-propyl)-6-(3-nitro-[1,2,4]triazol-1-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile in 41% yield.
