The procedure described in (a) is repeated, starting from 200 g (0.666 mole) of crude 3,12-dicyclopentyl-1,2-diaza-1,5,9-cyclododecatriene (diastereoisomer mixture) and using correspondingly reduced amounts of catalyst and solvent, affording after purification by chromatography and distillation 39.2 g (19% of theory) of 1,10-diamino-1,10-dicyclopentyl-decane as a colourless oil [b.p. 174°-178° C./0.002 torr; nD20 =1,4885; IR spectrum (liquid) includes bands at 3355, 3278, 1613-1 ].
