Procedure

A mixture of 0.512 g (0.00224 mol) of 1-(5-chloro-2,4-dihydroxy-3-propylphenyl)-ethanone, 1.000 g (0.00224 mol) of [4-acetyl-3-[2-[2-[(methylsulfonyl)oxy]ethoxy]ethoxy]-2-propylphenoxy]acetic acid ethyl ester and 0.620 g (0.00448 mol) of anhydrous potassium carbonate in 20 ml of anhydrous acetone and 10 ml of anhydrous dimethylformamide was stirred at reflux for 24 hours. The reaction mixture was filtered and concentrated in vacuo to an oil which was treated with ethyl acetate and sodium chloride solution. The crude oil obtained on concentration of the ethyl acetate was purified by column chromatography, eluting with 20-30% ethyl acetate-hexane to yield 0.400 g (31% yield) of [4-acetyl-3-[2-[2-(4-acetyl-6-chloro-3-hydroxy-2-propylphenoxy)ethoxy]ethoxy]2-propylphenoxy]acetic acid ethyl ester as a pale yellow oil.
