Reaction Steps
Reaction of 3-chloromethyl-4-methyloxazole with ethylenediamine by the procedure of Example 34 and reaction of the resulting N-(4-methyl-5-oxazolylmethyl)ethylenediamine with ethyl isothiocyanate by the procedure of Example 3(b) gives, after purifying by column chromatography, N-ethyl-N'-[2-(4-methyl-5-oxazolylmethylamino)ethyl]thiourea. This thiourea is reacted with lead cyanamide by the procedure of Example 3(b) to give N-cyano-N'-ethyl-N"-[2-((4-methyl-5-oxazolyl)methylamino)ethyl]guanidine.
