Procedure
3.0 G. of 4-acetylamino-3-trifluoromethylbenzenesulfonylchloride is dissolved in 15 ml. of concentrated sulfuric acid. 0.9 Moles of nitric acid is added dropwise over a period of 15 minutes, while the temperature is kept below 35° C. When the addition is complete the reaction mixture is stirred at room temperature for 2 hours. The reaction mixture is poured onto 150 ml. of ice water and the precipitate is filtered, washed with water and dried affording 4-acetylamino-3-nitro-5-trifluoromethylbenzenesulfonylchloride, used directly in the next step.
