Reaction Steps

To 0.186 g (1.0 mmol) of 2-(phenylsulfonyl)ethanol, 3 ml of acetonitrile was added, followed by 0.19 g (1.1 mmol) of methanesulfonic anhydride and 0.56 ml (4.0 mmol) of triethylamine, and the mixture was stirred for 5 hours at the internal temperature of 50° C. Subsequently, 0.37 g (1.5 mmol) of p-iodophenetole, 0.011g (0.05 mmol) of palladium acetate, and 0.067 g (0.22 mmol) of tri(o-tolyl)phosphine were added thereto, and the mixture was then refluxed for 17 hours. After cooled to room temperature, the reaction mixture was concentrated and purified by column chromatography (hexane/ethyl acetate=80/20) to obtain 0.158 g of [2-(phenylsulfonyl)ethenyl]-4-ethoxybenzene. Yield: 55%.
