Procedure
Reacting N-(2-benzimidazolylmethyl)ethylenediamine with N-cyano-N',S-dimethylisothiourea by the procedure of Example 36 gives N-[2-(2-benzimidazolylmethylamino)ethyl]-N'-cyano-N"-methylguanidine. Treating with hydrobromic acid gives the hydrobromide salt. Hydrolysis of this compound by the procedure of Example 3(e) gives N-[2-(2-benzimidazolylmethylamino)ethyl]-N'-methylguanidin trihydrochloride.
