0.48 g (1.3 mmol) of N-[2-[N-(4-methoxybenzyl)-N-(2-pyridyl)amino]ethyl]-N-methyl-1,6-hexanediamine and 0.27 g (1.3 mmol) of dicyclohexylcarbodiimide are dissolved at -10° C. in absolute ether with 0.5 ml of carbon disulfide, the temperature is increased in the course of 3 hours to 20° C. and the batch is stirred for a further 12 hours. The solid that precipitates is filtered off and the filtrate is concentrated in vacuo. 0.30 g (1.3 mmol) of 2-[[(2-guanidino-4-thiazolyl)methyl]thio]ethaneamine dissolved in a small amount of absolute ethanol is added to the concentrated residue and the reaction batch is heated under reflux for 2 hours. It is then concentrated in vacuo and the residue is purified by rotation chromatography to yield the purified title compound in the form of a viscous oil; MS (+FAB method): m/z (rel. int. [%])=644 ([M+H]+, 1), 121 (100). For further analysis, a portion of the compound is converted into the tartaric acid salt and recrystallised from acetonitrile/isopropanol/petroleum ether; m.p.: 78° C. (acetonitrile/isopropanol/petroleum ether).
