Versuchsvorschrift

9.9 Grams of 2-chloro sulphanilic acid and 9.4 grams of 4,7-dichloroquinoline were suspended in 200 milliliters of water and concentrated hydrochloric acid added until the solution was just acid. The mixture was refluxed for 4 hours when a solid began to precipitate. After cooling the solid was collected, washed with water and dried to give 15.8 grams of 4-(7-chloro-4-quinolylamino)-2-chlorobenzenesulphonic acid. Melting point 280°-285°C with decompostion.
