1,1'-Carbonyldiimidazole → N-[3-[N-[2-[N-(4-fluorobenzyl)-N-(2-pyridyl)amino]ethyl]-N-methylamino]propyl]-N'-[4-[3-(piperidinomethyl)phenoxy]butyl]urea

Participants

Reaction Steps

Preparation is effected analogously to Example 63, using 0.42 g (1.0 mmol) of N-[2-[N-(4-fluorobenzyl)-N-(2-pyridyl)amino]ethyl]-N-methyl-1,3-propanediamine and the equimolar amounts of 1,1'-carbonyldiimidazole and 4-[3-(piperidinomethyl)phenoxy]butylamine as starting materials. Working up by chromatography analogously to Example 63 yields the purified title compound in the form of a viscous oil; MS (+FAB method): m/z (rel. int. [%])=605 ([M+H]+, 14), 229 (100); IR (KBr): 1631 cm-1 (C=O). For further analysis, a portion of the compound is converted into the O,O'-ditoluoyltartaric acid salt and recrystallised from isopropanol/ether; m.p.: 115° C. (isopropanol/ether).
