Abstract
It has been shown that the reaction of heterocyclization of primary amines with orthoformic acid and sodium azide in acetic acid has a rather general character and is a convenient method for the synthesis if 1-substituted tetrazoles. On the basis of experimental data, a probable reaction mechanism is proposed.
