mild conditions, using a polymer‐supported nitrite reagent and p‐tosic acid. The functional group tolerance of this approach was further demonstrated with effective activation and cyclization of N‐alkyl, ‐aryl, and ‐acyl ortho‐aminoanilines leading to the synthesis of N1‐substituted benzotriazoles. The synthetic utility of this one‐pot heterocyclization process was exemplified with the preparation of a
