With stirring, a mixture of 16.9 g (0.1 mole) of 2-amino-4-dimethylamino-6-methoxy-1,3,5-triazine, 12 g (0.1 mole) of benztriazole, 9.4 g (0.11 mole) of aqueous 35% formaldehyde and 1 g of acetic acid in 100 ml of ethanol is heated under reflux for 2 hours. The still hot solution is clarified by filtration and crystals of the title compound precipitate from the cooled solution. The precipitate is filtered with suction and dried, affording 25 g (83% of theory) of crystalline product with a melting point of 222°-224° C.
