Modification of biologically active amides and amines with fluorine-containing heterocycles: 14.* Modification of the drug “riluzole” with an alkyne-azide “click”-reaction with pharmacologically active fragments

A synthetic approach to the modification of the drug “riluzole” with pharmacologically active fragments such as carbazole, tetrahydrocarbazole, phenothiazine, and aminothiophene, based on the copper-catalyzed alkyne-azide 1,3-dipolar cycloaddition of azide-containing pharmacophores with “riluzole” decorated with 5-trifluoromethylhydantoin, has been suggested.
