The procedure described in Example 1(a) is repeated, except that 215.3 g (1 mol) of N-benzylidene-(2-ethyl-1-hexenylamine) [1-phenyl-4-ethyl-4-n-butyl-2-aza-1,3-butadiene; prepared by reacting benzylamine with 2-ethyl-hexenal and then isomerising the reaction product with potassium tert.-butylate; boiling point 90° C./7 Pa; nD20 =1.5630] are used. Distillation yields 288 g (0.891 mol) of 3-n-butyl-3-ethyl-12-phenyl-1-aza-1,5,9-cyclododecatriene; boiling point 130° C./2 Pa; nD20 =1.5296.
