If there are used in the manner described under (a), instead of 942 g (3.79 mols) of 3,12-dipropyl-1,2-diaza-1,5,9-cyclododecatriene, 74.8 g (0.2 mol) of 3,12-di-(3-heptyl)-1,2-diazacyclododecane (diastereoisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, using otherwise the same procedure, there is obtained, after chromatographic purification and distillation, 29.9 g (40% of theory) of 6,15-diamino-5,16-diethyleicosane as colourless oil [b.p. 170° C./0.01 Torr; nD20 =1.4662; IR (liquid) inter alia bands at 3278 and 1613 cm-1 ].
