A mixture of 1.00 g (3.3 mmol) of 1-(6-bromohexyl)-2,3-dimethoxybenzene, 0.45 g (3.0 mmol) of 4-hydroxybenzoic acid methyl ester, 0.62 g (4.5 mmol) of potassium carbonate and 0.75 g (4.5 mmol) of potassium iodide in 25 mL of acetone was stirred at reflux for 23 hours. Workup as in Example 16 and purification by HPLC using 15% ethyl acetate-hexane gave 1.10 g (89% yield) of 4-[6-(2,3-dimethoxyphenyl)hexyloxy]benzoic acid methyl ester as an oil.
