To a solution of 10.5 g of 3-(tetradecyloxy)benzeneacetyl chloride in 110 ml of tetrahydrofuran is added a solution of m-aminobenzyl alcohol in 110 ml of tetrahydrofuran containing 9.05 g of pyridine followed by stirring at ambient temperature for 4 hours and storing in a refrigerator over the weekend. The solvent is evaporated and the residue is poured into water and extracted with tetrahydrofuran:ether. The organic layer is washed with dilute hydrochloric acid, dried and filtered through a pad of magnesium silicate. The filtrate is evaporated and the residue purified by high pressure liquid chromatography using 2:1 hexane:ethyl acetate to give 3.6 g of the desired product as a white powder, m.p. 108°-110° C. and 5.8 g of a white powder, m.p. 86°-90° C. found to be 3-(tetradecyloxy)-[3-[[[3-(tetradecyloxy)phenyl]acetyl]amino]phenyl]benzeneacetic acid methyl ester.
