The procedure described in Example 1(b) is repeated, except that 23.3 g (0.1 mol) of 3,3-dimethyl-12-isopropyl-1-aza-1,5,9-cyclododecatriene, 20 g of 37% hydrochloric acid, 20 ml of water and 11.15 g (0.1 mol) of semicarbazide hydrochloride are used. Working up yields 26.5 g (0.086 mol) of 2,2-dimethyl-11-isopropyl-11-amino-undeca-4,8-dienal semicarbazone; yield 86% of theory.
