Procedure

A mixture of 1 g (5.95 mmol) of 2,4-dihydroxybenzoic acid methyl ester, 1.98 g (5.95 mmol) of 1-bromooctadecane and 0.825 g (5.95 mmol) of potassium carbonate was stirred at reflux for 40 hours in 20 ml of acetone and 2 ml of DMF. The usual workup followed by purification by HPLC using 1% ethyl acetate-hexane gave 2-hydroxy -4-(octadecyloxy)benzoic acid methyl ester, mp 61°-64°.
