Synthesis of methyl 3-azidothieno[2,3-b]pyridine-2-carboxylates and application of the huisgen reaction

The preparation of new substituted methyl 3-azidothieno[2,3-b]pyridine carboxylates by azotization of methyl 3-aminothieno[2,3-b]pyridine and subsequent treatment with sodium azide is described. Via Huisgen's 1,3-dipolar cycloaddition between substituted alkynes and the prepared azides, methyl 1,2,3-triazolo-thieno[2,3-b]pyridine carboxylates have been obtained.
