Procedure

A mixture of 1.91 g (3.75 mmol) of 1-(6-bromohexyl)-2,3-bis[(4-methylbenzoyl)oxy]benzene, 1.07 g (3.75 mmol) 2,4-dihydroxy-3-propylbenzoic acid phenylmethyl ester, 0.94 g (5.63 mmol) of potassium iodide and 0.75 g (5.63 mol) of potassium carbonate in 40 mL of acetone was stirred at reflux for 26 hours. The reaction mixture was filtered and the filtrate was concentrated under reduced pressue. The crude product was purified by HPLC using 5% ethyl acetate-hexane to give 0.85 g (32% yield) of 2-hydroxy-4-[6-[2,3-bis[(4-methylbenzoyl)oxy]phenyl]hexyloxy]-3-propylbenzoic acid phenylmethyl ester as an oil.
