An operationally straightforward and efficient benzotriazole‐based method for the guanylation of diverse amines by use of the new reagent classes (bis‐benzotriazol‐1‐yl‐methylene)amines 13a – 13f and benzotriazole‐1‐carboxamidines 17a – 17i is described. The preparation is described for a variety of both acyclic and cyclic 1,2,3‐trisubstituted guanidines in high yields.
