Reaction Steps
A mixture of 29.2 g (0.097 mol) of 1-(6-bromohexyl)-2,3-dimethoxybenzene, 18.5 g (0.088 mol) of 2,4-dihydroxy-3-propylbenzoic acid methyl ester, 18.2 g (0.13 mol) of anhydrous potassium carbonate and 21.9 g (0.13 mol) of potassium iodide in 550 mL of anhydrous acetone was stirred at reflux for 22 hours. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure to an oil which was purified by HPLC using 8% ethyl acetate-hexane to give 31.4 g (83% yield) of 4-[6-(2,3-dimethoxyphenyl)hexyloxy]-2-hydroxy-3-propylbenzoic acid methyl ester as an oil.
