1,1'-bis(3-aminopropyl)-2,2'-diimidazole |
| 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° to 150° 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° to 200° C. under from 10 to 200 bar. |
