Procedure

To a solution of 115 ml nitric acid (d=1.42) in water (900 ml) are added successively 129.9 g (0.43 moles) of N-(2,6-diethylphenyl)-p-toluenesulfonamide, glacial acetic acid (900 ml) and sodium nitrite (3.2 g). The mixture is boiled on a steam bath for 1.5 hours, then poured into ice water (2 l). The precipitate is filtered, washed with water and air-dried to give crude N-(2,6-diethyl-4-nitrophenyl)-p-toluenesulfonamide.
