Versuchsvorschrift

A mixture of 21.7 g of p-tetradecyloxyphenylacetic acid and 11.85 g of oxalyl chloride, 45.5 mg of N,N-dimethylformamide and 250 ml of methylene chloride is stirred at ambient temperature for 24 hours. The solvent is removed by evaporation and the residue is dissolved in ether and filtered through diatomaceous earth. The filtrate is evaporated to give 22.3 g of the desired product as a white solid.
