Versuchsvorschrift
A mixture of 2-guanidino-4-(4-aminobutyl)thiazole (0.43 g.) and 1,1-dicyano-2-methylamino-2-methylthioethylene (0.3 g.) in acetonitrile (10 ml.) was heated under reflux for 16 hours. The mixture was then evaporated to dryness and the resulting gum purified by chromatography on a silica column using chloroform/methanol/ammonia (s.g. 0.880) 80:20:0.5 v/v/v as developing solvent to give 1-[4-(2-guanidinothiazol-4-yl)butylamino]-1-methylamino-2,2-dicyanoethylene.
