AbstractA convenient method is proposed for constructing the tetrazole ring by a one-pot reaction of amides with phosphorus oxychloride and sodium azide. A series of 1,5-disubstitutedtetrazoles containing an amino or a carboxy group, which present interest as buildings blocks for the synthesis of biologically active substances, were obtained.
