Versuchsvorschrift

8 g of 2-chloro-toluene-4-sulfonic acid chloride is dissolved in 25 ml of CHCl3 and slowly stirred into 100 ml of concentrated NH3 solution. After 10 minutes of stirring at room temperature, the solution is concentrated by evaporation to one-half of its original volume. The substance is suctioned off, washed with water and dried. 2-Chloro-4-sulfamoyltoluene is obtained.
