1,1'-Carbonyldiimidazole → N-[5-[N-[2-[N-(4-fluorobenzyl)-N-(2-pyridyl)amino]ethyl]-N-methylamino]-pentyl]-N'-[3-[3-(piperidinomethyl)phenoxy]propyl]urea

Participants

Reaction Steps

Preparation is effected analogously to Example 63, using 0.51 g (1.5 mmol) of N-[2-[N-(4-fluorobenzyl)-N-(2-pyridyl)amino]ethyl]-N-methyl-1,5-pentanediamine and the equimolar amounts of 1,1'-carbonyldiimidazole and 3-[3-(piperidinomethyl)phenoxy]propylamine 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. [%])=619 ([M+H]+, 3), 77 (100); IR (KBr): 1634 cm-1 (C=O). For further analysis, a portion of the compound is converted into the tartaric acid salt and recrystallised from isopropanol/ether/petroleum ether; m.p.: 63° C. (isopropanol/ether/petroleum ether).
