ABSTRACT:
An improved process for the preparation of 5-(4-aminobutyl)-hydantoin and/or 2-ureido-6-amino-hexanoic acid amide by the liquid phase hydrogenation of 5-(3-cyanopropyl)-hydantoin and/or 2-ureido-5-cyano-pentanoic acid amide in the presence of ammonia, hydrogen and a hydrogenation catalyst. Catalyst dissolution into the reaction medium is reduced by utilizing a hydrogenation catalyst in a solid bed form and causing the compounds to be hydrogenated to pass through such solid bed catalyst.
