ABSTRACT:
1,1'-bis(3-aminopropyl)-2,2'-diimidazole of the formula I ##STR1## is prepared by a novel process in which 2,2'-diimidazole of the formula II ##STR2## is reacted with acrylonitrile of the formula III ##STR3## in the presence of basic catalysts at from 80.degree. to 150.degree. C., and hydrogenation is carried out with excess hydrogen in the presence of ammonia on catalysts which contain cobalt, nickel, ruthenium and/or noble metals at from 40.degree. to 200.degree. C. under from 10 to 200 bar.
