Triazin-Derivate, Verfahren zu ihrer Herstellung und ihre Verwendung

摘要

The present invention provides a novel triazine derivative of the formula wherein ring A is an optionally substituted aromatic group which be; X is an oxygen or sulfur atom; R<1> and R<6> are each a hydrogen atom or an optionally substituted hydrocarbon residue or heterocyclic group which may bound through a heteroatom; R<2> and R<3> are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen or sulfur atom, or taken together, represent =S; R<4> and R<5> are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen, nitrogen or sulfur atom; R<1> and R<2>, and R<5> and R<6>, may each bind together to form a chemical bond; provided that where ring A is a phenyl group having at least a halogen atom in position-2 or 4 and X is an oxygen atom, R<4> and R<5> do not conjoinedly represent a chemical bond and an antiprotozoan composition containing the same or salt thereof.
