Hydrofluoric Acid → HCID 53844584, compound

Participants

Reaction Steps

A solution of rac-4-[4-[[(1,1 -dimethylethyl)dimethylsilyl]oxy]-4-(2-naphthalenyl) butoxy]-alpha-oxobenzeneacetic acid methyl ester (1.0 g) in acetonitrile (22.5 mL) containing 48% aqueous hydrofluoric acid solution (2.5 mL) was stirred at room temperature for 1 hour. The reaction mixture was poured into saturated sodium bicarbonate solution and extracted with ethyl acetate (3×10 mL). The combined organic extracts were dried (MgSO4) and evaporated to provide 0.76 g of crude product that was purified by flash chromatography over silica gel (ethyl acetate-hexane; 7:13) to yield 0.554 g of rac-4-[4-hydroxy-4-(2-naphthalenyl)butoxy]-alpha-oxobenzeneacetic acid methyl ester as an oil.
