A mixture of 0.74 g (2.5 mmol) of N-[3-(4-fluorophenyl)-3-(2-pyridyl)propyl]-N-methyl-1,3-propanediamine and an equimolar amount of 1-methylthio-1-[3-[3-(piperidinomethyl)phenoxy]propyl]amino-2-nitro-ethene is heated under reflux for 12 hours in 20 ml of acetonitrile. The batch is then freed from solvent and the title compound is isolated in the form of a viscous oil by means of preparative thick-layer chromatography (eluant: ethyl acetate/methanol 9+1, ammoniacal atmosphere); MS (+FAB method): m/z (rel. int.[%])=619 ([M+H]+ 2), 214 (100). For analytical purposes a sample is converted into the O,O'-ditoluoyltartaric acid salt and recrystallised from ether/isopropanol; m.p.: from 102° C. with decomposition.
