Reacting ethylenediamine with 5-benzyl-4-chloromethyloxazole by the procedure of Example 34, then reacting the resulting N-(5-benzyl-4-oxazolymethyl)-ethylenediamine with methyl isothiocyanate by the procedure of Example 3(b) and chromatographing gives N-methyl-N'-[2-((5-benzyl-4-oxazolyl)methylamino)ethyl]-thiourea. Reacting this thiourea with lead cyanamide by the procedure of Example 3(b) gives N-[2-((5-benzyl-4-oxaxzolyl)methylamino)ethyl]-N'-cyano-N"-methylguanidine
