Versuchsvorschrift

Reaction of 4-(4-aminobutyl)-5-methylimidazole (see Example 7 (ii), 2.71 g, 0.012 mol) with dimethylcyanodithioimidocarbonate (1.75 g 0.013 mol), gave S-methyl-N-cyano-N'-[4-(5-methyl-4-imidazolyl)butyl]isothiourea (2.27 g) which was treated directly with methylamine to yield N-cyano-N'-methyl-N"[4-(5-methyl-4-imidazolyl)butyl]guanidine (1.35 g), m.p. 152°-154° C. (from acetonitrile).
