実験手順

Under argon, 3.03 g (12.10-3 mol) of 3-cyano-4-iodobenzonitrile and 3.36 g (48.10-3 mol) of sodium thiomethylate are dissolved in 80 ml of anhydrous hexamethylphosphoramide and the solution obtained is then heated at 80° C. for 45 minutes. The resulting reaction medium is hydrolyzed in an ice/1N HCl mixture and then extracted with methylene chloride. The organic phase is washed with water and then dried over magnesium sulfate and evaporated under reduced pressure to give 1.55 g (yield: 81%) of the expected product.
