                                    A novel one-pot procedure for the preparation of N,6-disubstituted-1,3,5-triazine-2,4-diamines and its scope of application are demonstrated with a number of examples. The new procedure involves the treatment of isothiocyanates with sodium hydrogencyanamide, followed by amidines in the presence of 1-(3-dimethylaminopropyl)-3-ethylearbodiimide hydrochloride.
