Reaction Steps

A mixture of 1.0 g (2.9 mmole) of 4-[6-(2,3-dihydroxyphenyl)hexyloxy]-2-hydroxybenzoic acid, 0.295 g (3.5 mmole) of sodium bicarbonate and 2.4 mL (29 mmole) of ethyl iodide in 10 ml of anhydrous dimethylformamide was stirred at 50° for 6 hours. The solvent was removed on the oil pump and the residue was treated with sodium bicarbonate solution. The product was extracted with ethyl acetate and the dried extract was concentrated at reduced pressure to a solid. Recrystallization from ether-hexane gave 0.8 g, mp 63°-68°, (74% yield) of 4-[6-(2,3-dihydroxyphenyl)hexyloxy]-2-hydroxybenzoic acid ethyl ester.
