1,1'-Carbonyldiimidazole → HCID 178483547, compound

Participants

Reaction Steps

Preparation is effected analogously to Example 63, using 0.75 g (2 mmol) of N-[3-(4-chlorophenyl)-3-(2-pyridyl)propyl]-N-methyl-1,4-butanediamine, an equimolar amount of 1,1'-carbonyldiimidazole and 0.54 g (2.3 mmol) of 2-[[(2-guanidino-4-thiazolyl)methyl]thio]ethaneamine as starting materials. Working up by chromatography (eluant: methylene chloride/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.[%])=589 ([M+H]+, 2), 230 (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.: from 90° C. with decomposition.
