A mixture of 1.40 g (4.8 mmol) of 1-(6-bromohexyl)-2,3-dimethoxybenzene, 1.00 g (4.8 mmol) of 4-hydroxy-3-propylbenzoic acid ethyl ester, 1.30 g (9.6 mmol) of potassium carbonate and 0.72 g (4.8 mmol) of sodium iodide in 35 mL of acetone was stirred at reflux for 47 hours. Workup and purification as described in Example 16 gave 2.0 g of 4-[6-(2,3-dimethoxyphenyl)hexyloxy]-3-propylbenzoic acid ethyl ester as an oil. The mass spectrum showed the molecular ion at m/e 428.
