Reaction Steps

To a suspension of trimethylsulfoxonium iodide (1.36 g, 6.1 mmol) in 7.7 mL of anhydrous DMSO was added sodium hydride (60% dispersion in mineral oil, 246 mg). The resulting solution was stirred at room temperature for 30 minutes and was then added dropwise to a solution of 1,1,1-trifluoro-4-methyl-4-(5-methylsulfanyl-2,3-dihydrobenzofuran-7-yl)pentan-2-one (1.63 g, 6.2 mmol) in 6.5 mL of anhydrous DMSO. After 2 hours, 100 mL of water was added and the resulting mixture was extracted with three 100 mL portions of diethyl ether. The combined organic phases were washed twice with water, aqueous saturated sodium chloride solution, dried over magnesium sulfate, filtered, and concentrated in vacuo to afford the title compound, 1.64 g (95% yield) which was used without further purification.
