Procedure

A mixture of 100.0 g of 3-chloro-4-(hydroxy)benzoic acid methyl ester, 148.6 g of 1-bromotetradecane, 170.4 g of potassium carbonate and 1 L of acetone is heated at reflux temperature for 40.5 hours. The cooled reaction is filtered, concentrated in vacuo and purified by column chromatography (silica gel:0-2% ethyl acetate/hexane) to give 197.1 g of the desired product as colorless crystals.
