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, 328.5 g (1 mol) of 3,12-dicyclohexyl-1,2-diaza-1,5,9-cyclododecatriene (diastereoisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, with otherwise the same procedure, there is obtained, as the main fraction, 304 g (90% of theory) of 1,10-diamino-1,10-dicyclohexyldecane in the form of colourless oil [b.p. 190°-193° C./0.05 Torr; nD20 =1.4944; IR (liquid) inter alia bands at 3355, 3278 and 1613 cm-1 ].
