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, 49 g (0.159 mol) of 3,12-di-(3-pentyl)-1,3-diazacyclododecane and correspondingly reduced amounts of catalyst and solvent, there is obtained, after chromatographic purification and distillation, 26.8 g (54% of theory) of 4,13-diamino-3,14-diethylhexadecane as colourless oil [b.p. 141°-143° C./0.004 Torr; nD° =1.4666; IR (liquid) inter alia bands at 3378, 3278 and 1613 cm-1 ].
