If there are used in the manner described under (a), intead of 942 g (3.79 mols) of 3,12-dipropyl-1,2-diaza-1,5,9-cyclododecatriene, 250 g (1 mol) of 3,12-diisopropyl-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, as the main fraction, 238 g (92% of theory) of 3,12-diamino-2,13-dimethyltetradecane as colourless oil [b.p. 106°-109° C./0.01 Torr; nD20 =1.4600; IR (liquid) inter alia bands at 3355, 3278 and 1613 cm-1 ].
