Vorschrift

To a solution of 149.0 g (1.0 mole) of 2,6-diethylaniline in pyridine (500 ml) is added in portions at 0° C. 209.6 g (1.1 moles) of p-toluenesulfonyl chloride. The reaction mixture is allowed to come to room temperature and stir for three hours. The mixture is poured into cold aqueous 10% HCl and the crude sulfonamide solidified. The sulfonamide is filtered, washed with water and crystallized from acetic acid to give N-(2,6-diethylphenyl)-p-toluenesulfonamide m.p. 130°-131° C.
