Versuchsvorschrift

A mixture of 100 g of 2-cyclopropylamino-4-amino-6-chloro-s-triazine, 51 g of ammonia and 500 ml of dioxan is heated at 140° C. in an autoclave for 24 hours. After cooling, the dioxan is removed by filtering with suction in vacuo and the crystalline residue is washed with water and dried. The crude product is recrystallised from methanol; melting point 219°-222° C.
