Preparation is effected analogously to Example 1, using 0.75 g (2.1 mmol) of N-[3-(4-chlorophenyl)-3-(2-pyridyl)propyl]-N-methyl-1,5-pentanediamine and 0.81 g (2.1 mmol) of N-cyano-N'-[2-[[(2-guanidino-4-thiazolyl)methyl]thio]ethyl]-O-phenyl-isourea as starting materials. Working up by chromatography analogously to Example 1 yields the purified title compound in the form of a dry foam; MS (+FAB method): m/z (rel. int.[%])=627 ([M+H]+, 3), 230 (100); IR (KBr): 2162 cm-1 (C≡N). For analytical purposes a sample is converted into the maleic acid salt and recrystallised from ether/ethanol; m.p.: 87°-90° C.
