Abstract: Alkylation of 5-(5-bromo-2-furyl)-l#-tetrazole with ethyl bromoacetate afforded a mixture of ethyl 5-(5-bromo-2-furyl)-l-tetrazolylacetate and ethyl 5-(5-bromo-2-furyl)-2-tetrazolylacetate; these were chromatographically separated and the ester substituted in position 1 was the substrate for the nucleophilic substitution with 4-substituted thiophenols. The resulting ethyl 5-[5-(4-R-phenylthio)-2-furyl]-l-tetrazolylacetates were hydrolyzed to corresponding acids.
