Vorschrift

245 mg of (E)-N-methyl-N-(6,6-dimethyl-2-hepten-4-ynyl)-3-hydroxybenzylamine was dissolved in 5 ml of tetrahydrofuran, and under ice cooling, 40 mg of oily sodium hydride was added. After the mixture was stirred for 15 minutes, a dimethylformamide solution (3ml) of 125 mg of (E)-1,4-dichloro-2-butene was added. The mixture was stirred at room temperature for 12 hours, and then the solvent was evaporated. The residue was worked up in a customary manner, and purified by silica gel column chromatography [hexane/ethyl acetate=5/1] to give 216 mg of the captioned compound as a colorless oil.
