FIELD: organic chemistry. SUBSTANCE: product: derivatives of 2-anilinopyrimidine of the general formula , where R1 and R2 are independently each of other mean hydrogen, halogen, C1-C3-alkyl, C1-C2-halogenalkyl, C1-C3-alkoxy or C1-C3-halogenalkoxy; R3 - hydrogen, C1-C4-alkyl, or C1-C4-alkyl substituted with hydroxy-group, cyclopropyl or cyclopropyl substituted with methyl; R4-C3-C6 -cyclopropyl or substituted similarly or differently with methyl and/or halogen up to triple, (C3-C6)-cycloalkyl. Reagent 1: phenylguanidine salt of the general formula , where A⊖ - anion of mineral acid, or guanidine of the general formula . Reagent 2: diketone: R3C(O)CH2C(O)R4. Cyclization is carried out at 60-160 C. Synthesized compounds are used in agriculture as fungicides and insecticides. EFFECT: improved method of synthesis.
