The procedure described in Example 2(b) is repeated, except that 68.5 g (0.5 mol) of 3,3-dimethyl-12-isopropyl-1-aza-cyclododecene, 50 g of 37% hydrochloric acid, 54 g (0.5 mol) of benzylamine and 200 ml of water are used. After neutralisation with 22 g (0.55 mol) of solid sodium hydroxide, 97 g (0.282 mol) of 2,2-dimethyl-11-isopropyl-11-amino-undecanal-benzylamine are obtained; yield 56.4% of theory.
