Reacting ethylenediamine with 2-chloromethylthiazole by the procedure of Example 34, then reacting the resulting N-(2-thiazolylmethyl)ethylenediamine with N-cyano-N',S-dimethylisothiourea by the procedure of Example 3(a), gives N-cyano-N'-methyl-N"-[2-(2-thiazolylmethylamino)ethyl]guanidine. Hydrolysis of this compound by the procedure of Example 3(e) gives N-methyl-N'-[2-(2-thiazolylmethylamino)ethyl]guanidine trihydrochloride.
