4.4 g of N,N-dimethylethylenediamine was dissolved in 40 ml of dioxane. 5 ml of pyridine was added to the solution. 17.6 g of 3,7,11,15-tetramethyl-2,6,10,14-hexadecatetraenyl bromide was added thereto and the mixture was heated under reflux for 2 h and poured in ice-water. After extraction with n-hexane followed by washing with water and concentration, the resulting reaction mixture was treated by alumina column chromatography to obtain 6 g (33%) of the title compound as a colorless oil.
