Abstract
A process for preparing 1-[1,5-di-(3,3-dimethylnorborn-2-yl)-3-pentyl]-1,5,9-triazanonane from 1,5-di-(3,3-dimethylnorborn-2-yl)-3-pentanone by reaction with ammonia to form, after reduction, 3-amino-[1,5-di-(3,3-dimethylnorborn-2-yl)pentane]. This latter compound is reacted with acrylonitrile, reduced, and the diamine product again reacted with acrylonitrile and again reduced. Alternative routes wherein the ketone is reduced to the novel alcohol and optionally the novel halide and either then reacted with 3,3'-iminobispropylamine to form the desired polyamine are also shown.
