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, 200 g (0.666 mol) of crude 3,12-dicyclopentyl-1,2-diaza-1,5,9-cyclododecatriene (diasterioisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, the procedure otherwise being the same, there is obtained, after chromatographical purification and distillation, 39.2 g (19% of theory) of 1,10-diamino-1,10-dicyclopentyldecane in the form of 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 ].
