The invention pertains to a process for manufacturing a nitrile compound through chain elongation of an alkylene amine compound containing three or more amine units in which at least two amine units are protected by a cyclic urea unit and at least one amine unit is not protected, by reacting the at least one amine unit that is not protected with glycolonitrile or with the combination of formaldehyde and a cyanide compound selected from HCN and inorganic cyanide salts, to add at least one acetonitrile group to the at least one amine unit that is not protected. The process according to the invention allows manufacture of nitrile compounds in high selectivity and high yield. The nitrile compounds can be processed as desired.
