Procedure
Reacting N-(2-thiazolylmethyl)ethylenediamine with ethyl isothiocyanate by the procedure of Example 3(b) and then chromatographing gives N-ethyl-N'-[2-(2-thiazolylmethylamino)ethyl]thiourea. Reacting this thiourea with lead cyanamide by the procedure of Example 3(b) gives N-cyano-N'-ethyl-N"-[2-(2-thiazolylmethylamino)ethyl]guanidine.
