FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to the improved method for preparing compounds of the formula (I) 
or their salts. Compounds of the formula (I) can be synthesized by the chlorination reaction of compounds of the formula (II) 
wherein X means hydrogen atom (H), (C1-C6)-alkyl; R1 means (C1-C6)-alkyl substituted with halogen atom(s); R2 and R3 mean hydrogen atom (H) in the presence of a water-free protonic organic solvent. Proposed compounds are useful for preparing active substances among class of aminotriazines, for example, herbicide active substances.
EFFECT: improved preparing method.
