FIELD: organic chemistry and chemical technology. SUBSTANCE: triazines of the formula (I) <EMI ID=0.286 HE=27 WI=33 TI=CHI> synthesized by simple procedure are valuable intermediate substances for synthesis of dyes, drugs and agents for plant protection. Invention relates to asymmetrically substituted triazines of the general formula (I) where R - hydrogen, methyl or ethyl; R and R mean C<SB>1-8</SB>-alkyl, C<SB>3-8</SB>-alkenyl, C<SB>3-8</SB>-alkynel, C<SB>3-8</SB>-cycloalkyl, phenyl, benzyl or phenethyl each of that can be substituted with fluorine, chlorine, phenyl, C<SB>1-4</SB>-alkyl or C<SB>1-4</SB>-alkoxyl that are synthesized by an interaction of quanidine derivative of the formula (II) <EMI ID=0.287 HE=21 WI=30 TI=CHI> with carboxylic acid derivative (IV) given in description where R can has any values indicated for R . Reaction is carried out in the presence of alcohol R -OH and a base or carboxylic acid amide in the presence of salt or salt-like compound of magnesium, calcium, aluminium, zinc, copper, iron, cobalt, nickel or chrome. Method provides synthesis of triazines of the formula (I) from more available raw exhibiting less reactive capacity. Method can be carried out without isolation of intermediate compounds. EFFECT: improved and simplified method of synthesis. 13 cl, 6 ex
