Versuchsvorschrift

A solution of N-benzenesulphonyliminodithiocarbonic acid dimethyl ester (13.0 g.) and 4-methyl-5-((2-aminoethyl)thiomethyl)imidazole (8.5 g.) in ethanol (100 ml.) was stirred at room temperature for 4 hours. Excess ethanolic methylamine was added and stirring was continued for 2 hours at room temperature. Following concentration, the residue was dissolved in ethanol-ether (1:1) and chilled affording N-benzenesulphonyl-N'-methyl-N"-[2-((4-methyl-5-imidazolyl)methylthio)-ethyl]guanidine (15.0 g.), m.p. 156.5 - 157.5 (from water)
