Abstract: 5-[5-(Substituted phenylthio)-2-furyl]tetrazol-l-ylacetic acids were pre­pared from ethyl 5-(substituted phenylthio)-2-furylcarbamidoacetates and phosphorus pentachloride via the corresponding imidoyl chlorides, which on treatment with sodium azide afforded the appropriate ethyl 5-[5-(substituted phenylthio)-2-furyl]tetrazolylacetates. Free acids serving as an inter­mediate in preparation of semisynthetic cephalosporins were obtained by an alkaline hydrolysis.
