The procedure described in Example 1(b) is repeated, except that 233.4 g (1 mol) of 3,3-dimethyl-12-isopropyl-1-aza-1,5,9-cyclododecatriene, 100 g of 37% hydrochloric acid, 200 ml of water and 69.5 g (1.0 mol) of hydroxylamine hydrochloride are used. Working up and subsequent distillation yields 245 g (0,92 mol) of 2,2-dimethyl-11-isopropyl-11-amino-undeca-4,8-dienal oxime; yield 92% of theory; boiling point 158°-162° C./4 Pa; nD20 =1.4930.
