If there are used in the manner described under (a), instead of 250 g (1 mol) of 3,12-diisopropyl-1,2-diaza-1,5,9-cyclododecatriene, 35.9 g (0.09 mol) of crude 3,12-di-(4-octyl)-1,2-diaza-1,5,9-cyclododecatriene and correspondingly reduced amounts of catalyst and solvent, with otherwise the same procedure, there is obtained, after chromatographical purification and bulb-tube distillation, 8.8 g (24% of theory) of 6,15-diamino-5,16-dipropyleicosane in the form of colourless oil [nD20 =1.4655; IR (liquid) inter alia bands at 3380, 3300 and 1623 cm-1 ].
