Reaction Steps

A mixture of 5.0 g (0.01 mol) of 3-hydroxy-5-(octadecyloxy)benzoic acid phenylmethyl ester, 10.2 ml (0.1 mol) of 1,3-dibromopropane and 7.0 g (0.05 mol) of potassium carbonate in 75 ml of acetone and 15 ml of DMF was stirred at reflux for 22 hours. The reaction mixture was filtered and the filtrate was concentrated at reduced pressure to an oil. Purification by HPLC using 5% ethyl acetate-hexane gave 4.91 g (79% yield, mp 57°-58°) of 3-(3-bromopropoxy)-5-(octadecyloxy)benzoic acid phenylmethyl ester. The structure was confirmed by the nmr spectrum.
