Reaction Steps

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, 87.3 g (0.31 mol) of 3,12-di-(2-butyl)-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, 74.7 g (85% of theory) of 4,13-diamino-3,14-dimethylhexadecane in the form of colourless oil [b.p. 143°-5° C./0.05 Torr; nD20 =1.4639; IR (liquid) inter alia bands at 3330 and 1626 cm-1 ].
