1,1'-Carbonyldiimidazole → N-[4-[N-[3-(4-fluorophenyl)-3-(2-pyridyl)propyl]-N-methylamino]butyl]-N'-[2-[[(2-guanidino-4-thiazolyl)methyl]thio]ethyl]urea

Participants

Reaction Steps

Preparation is effected analogously to Example 63, using 0.95 g (3.5 mmol) of N-[3-(4-fluorophenyl)-3-(2-pyridyl)propyl]-N-methyl-1,4-butanediamine, an equimolar amount of 1,1'-carbonyldiimidazole and 0.82 g (3.5 mmol) of 2-[[(2-guanidino-4-thiazolyl)methyl]thio]ethaneamine as starting materials. Working up by chromatography (eluant: ethyl acetate/methanol 9+1) analogously to Example 63 yields the purified title compound in the form of a dry foam; MS (+FAB method): m/z (rel. int.[%])=573 ([M+H]+ 2), 214 (100); IR (KBr): 1632 cm-1 (C=O). For analytical purposes a sample is converted into the O,O'-ditoluoyltartaric acid salt and recrystallised from ether/isopropanol; m.p.: from 120° C. with decomposition.
