| —— | methyl 1-(4-propyl-1H-1,2,3-triazol-1-yl)-6,7-dihydrobenzo[f]thieno[2,3-c]isoquinoline-2-carboxylate | 1644599-72-3 | C22H20N4O2S | 404.492 |
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.
