To a solution of 1,1,1-trifluoro-4-(5-bromo-2-methoxyphenyl)-4-methylpentan-2-one (5 g, 14.7 mmol) in 5 mL of anhydrous DMSO at room temperature was added 14.6 mL of the ylide stock solution (17.3 mmol) over 5 minutes. The reaction was quenched after 2 hours with water and diethyl ether. The aqueous layer was extracted with diethyl ether. The combined organic layers were washed with water and brine, dried over magnesium sulfate, filtered, and concentrated in vacuo to afford 2-[2-(5-bromo-2-methoxyphenyl)-2-methylpropyl]-2-trifluoromethyloxirane as a dark yellow oil.
