Versuchsvorschrift
The obtained (Z)-11-heptadecenol (Formula II, R=CH3) is added to a mixture of 5 ml. of dry pyridine and 3.5 ml of acetic anhydride, and the mixture is stirred at 0° C. for 3 hours. The solution is poured onto ice and extracted with methylene chloride. The extract is washed with water, 3% aqueous sulfuric acid and again with water, dried over magnesium sulfate, filtered, and the solvent is evaporated. The residue is distilled in fine vacuo. 2.25 g (42%) of (Z)-11-heptadecenyl acetate (Formula I, R=CH3) are obtained; this compound is identical with the product obtained in step (A) above.
