Reaction Steps

To a solution of 1-[4-(pentafluoro-λ6-sulfanyl)phenyl]ethanone (Preparation 41, 0.6 g, 2.44 mmol) in THF (20 mL) at 0° C. was added trimethylphenylammonium tribromide (0.962 g, 2.56 mmol). After stirring for 2 hours at 0° C. the reaction was quenched with a saturated aqueous solution of sodium hydrogen carbonate. The reaction was extracted with ethyl acetate and dried over MgSO4 before concentrating in vacuo to afford the title compound that was used without further purification.
