Preparation is effected analogously to Example 1, using 0.33 g (1.0 mmol) of N-[2-[N-(4-fluorobenzyl)-N-(2-pyridyl)amino]ethyl]-N-methyl-1,4-butanediamine and the equimolar amount of N-cyano-O-phenyl-N'-[3-[3-(piperidinomethyl)phenoxy]propyl]isourea as starting materials. Working up by chromatography analogously to Example 1 yields the purified title compound in the form of a viscous oil; MS (+FAB method): m/z (rel. int. [%])=629 ([M+H]+, 5), 229 (84), 109 (100); IR (KBr): 2166 cm-1 (C≡N). For further analysis, a portion of the compound is converted into the tartaric acid salt and recrystallised from ethanol/acetonitrile/isopropanol; m.p. 84°-86° C. (ethanol/acetonitrile/isopropanol).
