Participants

Reaction Steps

A solution of 4-chlorophenol (5.54 g, 43 mmol) in DMSO (75 mL) was treated sequentially with potassium t-butoxide (5.15 g, 46 mmol) then with a solution of 4-fluorophenyl methyl sulfone (5.00 g, 29 mmol) in DMSO (25 mL), heated at 120° C. for 2 hours, cooled to room temperature, then partitioned between dichloromethane and 1 N sodium hydroxide, dried (Mg2SO4), filtered, and concentrated to give crude product as a white solid. Recrystallization from ethyl acetate and hexane afforded 5.44 g (66%) of the desired product.
