Procedure

By the procedure of Example 3(b), reacting N-(3-pyrazolylmethyl)ethylenediamine with ethyl isothiocyanate, then reacting the resulting N-ethyl-N'-[2-(3-pyrazolylmethylamino)ethyl]thiourea with lead cyanamide gives N-cyano-N'-ethyl-N"-[2-(3-pyrazolylmethylamino)ethyl]guanidine. By the same procedure, using propyl isothiocyanate the corresponding N'-propyl compound is prepared. Also, by the same procedure, using 2-dimethylaminoethyl isothiocyanate, the product is N-cyano-N'-(2-dimethylaminoethyl)-N"-[2-(3-pyrazolylmethylamino)ethyl]-guanidine.
