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

Participants

Reaction Steps

Preparation is effected analogously to Example 63, using 0.85 g (3 mmol) of N-methyl-N-[3-phenyl-3-(2-pyridyl)propyl]-1,3-propanediamine, an equimolar amount of 1,1'-carbonyldiimidazole and 0.75 g (3.2 mmol) of 2-[[(2-guanidino-4-thiazolyl)methyl]thio]ethaneamine as starting materials. Working up by chromatography (eluant: chloroform/methanol 9+1) analogously to Example 63 yields the purified title compound in the form of an oil; MS (+FAB method): m/z (rel. int. [%])=541 ([M+H]+, 2), 196 (100); IR (KBr): 1650 cm-1 (C=O). For analytical purposes a sample is converted into the maleic acid salt and recrystallised from ether/ethanol; m.p.: 95°-98° C.
