An improved method of producing 3-amino-1,2,4-benzotriazines using nitrobenzene or a derivative thereof, a guanidine salt and a base as reactants is provided. The method is carried out at a moderate reaction temperature without producing halide wastes derived from nucleophilic substitution and acid byproducts.
