Versuchsvorschrift

33.5 g of the 2,6-bis(β-chloroethoxycarbamoylamino)toluene obtained above under the 1st stage are initially introduced into the reaction vessel in 200 ml of water and 30 ml of methanol. The reaction mixture is heated to 75° C. and 70 g of 50% strength potassium hydroxide solution are added dropwise in the course of one hour. After the mixture has been subsequently stirred at 60° C. for 21/2 hours, the pH is brought to 8.0 with glacial acetic acid and the reaction mixture is cooled slowly. The product which has precipitated is filtered off with suction, washed with water, and dried at 50° C. in a vacuum cabinet.
