Versuchsvorschrift

A mixture of 66 g of 3-hydroxyphenethyl alcohol, 147.43 g of 1-bromotetradecane, 27.65 g of sodium hydroxide and 2.15 g of trioctylmethyl ammonium chloride in 400 ml of toluene was refluxed for 42 hours. The mixture was washed with water and the organic layer dried with magnesium sulfate. The solvent was removed in vacuo and the warm concentrate poured into 1 liter of hexanes. The resulting solid was washed with cold hexanes then dried giving 998.6 g of the desired compound as a white solid.
