Versuchsvorschrift

A mixture of 200 g of methyl 4-hydroxyphenylacetate, 350.4 g of 1-bromotetradecane, 207.9 g of potassium carbonate, 10 g of potassium iodide and 1.5 L of acetone is heated at reflux temperature for 24 hours. The reaction is cooled to room temperature, concentrated in vacuo and the residue is recrystallized from cold hexane to give 276.0 g of the desired product.
