Potassium Carbonate → 4-[4-Acetyl-3-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)propoxy]-2-propylphenoxy]butanoic acid ethyl ester

Participants

Reaction Steps

A mixture of 3.00 g of 1-(2,4-dihydroxy-3-propylphenyl)ethanone, 6.65 g of 4-[4-acetyl-3-(3-bromopropoxy)-2-propylphenoxy]butanoic acid ethyl ester and 4.30 g of anhydrous potassium carbonate in 100 ml of anhydrous acetone and 50 ml of anhydrous dimethylformamide was stirred at reflux for 19 hours. The solvent was removed in vacuo to give a red oil which was purified by high pressure liquid chromatography to yield 6.42 g (76%) of 4-[4-acetyl-3-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)propoxy]-2-propylphenoxy]butanoic acid ethyl ester as an oil.
