Reaction Steps
A mixture of 100 g of 2-cyclopropylamino-4-chloro-6-amino-s-triazine, 51 g of anhydrous ammonia and 500 ml of dioxane is heated for 24 hours in an autoclave at 140° C. After cooling to room temperature the solvent is removed by water jet vacuum distillation. 300 ml of water are added to the residue. After stirring, the residue product is filtered off and recrystallised from boiling ethanol. 50 g of 2-cyclopropylamino-4,6-diamino-s-triazine are obtained. Melting point: 219°-222° C.
