2-mercapto substituted triazolopyrimidines, methods for preparing them, their use for controlling pathogenic fungi, and medicaments comprising 2-mercapto substituted triazolopyrimidine compounds

摘要

The present invention relates to a process for the preparation of a compound of formula (I) in which the substituents have the following meanings: L is halogen, cyano, nitro, alkyl, alkenyl, alkynyl, halogenalkyl, halogenalkenyl, alkoxy, alkenyloxy, alkynyloxy A represents hydrogen, hydroxy, alkyl, alkenyl, alkoxy, halogenalkoxy, alkylamino or dialkylamino; m represents 0, 1, 2, 3, 4 or 5; X represents halogen, cyano, alkyl, halogenalkyl, alkoxy or halogenalkoxy; R¹And R²Represents a hydrogen, alkyl, halogenalkyl, cycloalkyl, halogencycloalkyl, alkenyl, alkadienyl, halogenalkenyl, cycloalkenyl, alkynyl, halogenalkynyl, cycloalkynyl, phenyl or naphthyl, or represents a group of O, N or S A 5-to 10-membered saturated, partially unsaturated or aromatic heterocyclic ring containing 1 to 4 heteroatoms selected from R¹And R²Together with the nitrogen atom to which they are attached form a 5-or 6-membered ring wherein the ring is interrupted by an atom selected from the group of O, N and S Alternatively, where R¹And / or R²Are optionally substituted as described herein, to 2-mercapto substituted triazolopyrimidines. The invention also relates to a process for preparing the above compound, to a medicament comprising said compound and to their use for controlling phytopathogenic fungi.
