Potassium Carbonate → [[8-Acetyl-7-[3-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)propoxy]propoxy]-2-naphthalenyl]oxy]acetic acid methyl ester

Participants

Reaction Steps

A mixture of 1.73 g of [[8-acetyl-7-[3-(3-bromopropoxy)propoxy]-2-naphthalenyl]oxy]acetic acid methyl ester, 0.89 g of 1-(2,4-dihydroxy-3-propylphenyl)ethanone and 0.79 g of anhydrous potassium carbonate in 33 ml of anhydrous acetone and 11 ml of anhydrous dimethylformamide was stirred at reflux for 18 hours. The mixture was filtered and filtrate was concentrated in vacuo to an oil. Purification by high pressure liquid chromatography (10% ethyl acetate-toluene) gave 1.2 g (56%) of [[8-acetyl-7-[3-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)propoxy]propoxy]-2-naphthalenyl]oxy]acetic acid methyl ester.
