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, 100 g (0.21mol) of crude 3,12-diundecyl-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 64.3 g (64% of theory) of 12,21-diaminodotriacontane [m.p. 45°-46° C.; IR (CH2Cl2) inter alia bands at 3174 and 1582 cm-1 ].
