실험 절차

Probucol (5, 9.69 mmol) and methyl 4-chlorobutyrate (3.1 g. 1.4 eq) were stirred in DMF (15 mL) and potassium fluoride on alumina (7 g, 5 eq) was added. The mixture was stirred at room temperature under nitrogen for 20.5 hours. It was filtered, diluted with ethyl acetate (100 mL), washed with water and brine, dried over sodium sulfate, and evaporated. Chromatography (MPLC, 10% to 80% of dichloromethane in hexanes) gave 0.98 g of methyl 4-[4-[[1-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]thio]-1-methylethyl]thio]-2,6-bis(1,1-dimethylethyl)phenoxy]butyrate.
