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, 200 g (0.666 mol) of crude 3,12-dicyclopentyl-1,2-diaza-1,5,9-cyclododecatriene (diastereoisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, with the procedure otherwise being the same, there is obtained, after chromatographic purification and distillation, 39.2 g (19% of theory) of 1,10-diamino-1,10-dicyclopentyldecane as colourless oil [b.p. 174°-178° C./0.002 Torr; nD20 =1.4885; IR (liquid) inter alia bands at 3355, 3278 and 1613 cm-1 ].
