The procedure described in (a) is repeated, starting from 49 g (0.16 mole) of 3,12-di-(3-pentyl)-1,2-diazacyclododecane and using correspondingly reduced amounts of catalyst and solvent, affording after purification by chromatography 37.5 g (75% of theory) of 4,13-diamino-3,14-diethylhexadecane as a colourless oil [nD20 =1.4664; IR spectrum (liquid) includes bands at 3330, 1626 cm-1 ].
