In a mixture of 20 ml of dimethyl sulfoxide and 12 ml of tetrahydrofuran were dissolved 2.2 g of 3-(3,7, 11,15-tetramethyl-2,6,10,14-hexadecatetraenyl bromide and 2.3 g of 2-O-methylglycerin, and 2.0 g of powdered potassium hydroxide was added. The mixture was stirred for 2 hours, poured into cold water and extracted with ethyl acetate. The extract was washed with water, dried and concentrated. The residue was purified by chromatography on a silica gel column to give 1.15 g of the above-identified compound as light-yellow liquid.
