FIELD: chemistry.

SUBSTANCE: invention relates to novel pyrimidine derivatives of formula (1) in free form or in form of a salt. In formula (1): X₁ and X₂ all independently denote halogen; A denotes a radical of formula where (R₁)_1-2 denotes 1-2 identical or different substitutes selected from a group comprising C₁-C₄-alkyl, halogen-C₁-C₄-alkyl, hydroxy-C₁-C₄-alkyl, C₁-C₄-alkoxy-C₁-C₄-alkyl, R₂R₃N-C₁-C₄-alkyl, halogen, hydroxy group, C₁-C₄-alkoxy group, halogen-C₁-C₄-alkoxy group, C₁-C₄-alkylthio group, C₁-C₄-alkanoyl, C₁-C₄-alkanoylamino group, C₁-C₄-alkylsulphonylamino group, C₁-C₄-alkylsulphonyl, C₁-C₄-alkylthionyl, NR₂R₃ and morpholinyl; or A denotes a radical of formula where ring (a) denotes a 5-member heterocyclic ring containing 1 or 2 heteroatoms selected from a group comprising O and N, which can further be substituted with C₁-C₄-alkyl, and which is annelated in positions 3 and 4; and R₂ and R₃ all independently denote hydrogen or C₁-C₄-alkyl. The invention also relates to a parasite control composition containing said compounds, a parasite control method on warm-blooded animals and use of compounds of formula (1) to prepare a parasite control composition.

EFFECT: high efficiency of using said compounds.
