実験手順

1.25 g of sodium thiomethylate are added under a nitrogen atmosphere to a solution of 15 g (0.0593 mol) of 1-chloro-4-(phenylsulfonyl)benzene in 150 ml of hexamethylphosphoramide. The mixture obtained is heated for 4 hours at 100° C. and then cooled and hydrolyzed in an ice/water mixture. The reaction medium obtained is extracted with ethyl acetate and the aqueous phase obtained is then poured into a 4 N solution of hydrochloric acid at 0° C. The product formed precipitates. After filtration, washing with water until the pH of the washings is neutral, and drying, 13.44 g (yield: 90.5%) of the expected product are obtained. M.p.=117° C.
