Preparation is effected analagously to Example 63, using 0.50 g (1.5 mmol) of N-[2-[N-(4-fluorobenzyl)-N-(2-pyridyl)amino]ethyl]-N-methyl-1,4-butanediamine and the equimolar amounts of 1,1'-carbonyldiimidazole and 2-[[5-[(dimethylamino)methyl]furfuryl]thio]ethylamine 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. [%])=571 ([M+H]+, 109 (100); IR (KBr): 1640 cm-1 (C=O). For further analysis, a portion of the compound is converted into the tartaric acid salt in an ethanol/ether solvent mixture; m.p.: 74° C. (ethanol/ether).
