<p>Method for the preparation of aminotriazine derivatives of the formula <IMAGE> in which R is hydrogen, C1-C6-alkyl, C3-C6-cycloalkyl, C1-C4-alkyl which is substituted by 1 to 10 halogen atoms or 1 to 3 radicals from the group comprising C1-C3-alkoxy, C1-C3-alkylthio or phenyl, or is phenyl, or phenyl which is substituted by 1 to 3 radicals from the group comprising halogen, methyl, ethyl, methoxy, methylthio or nitro, characterised in that a compound of the formula II <IMAGE> in which R1 is hydrogen, C1-C4-alkyl, C2-C6-cycloalkyl, C1-C4-alkyl which is substituted by 1 to 9 chlorine atoms, C1-C3-alkoxy, C1-C3-alkylthio, C1-C3-alkylsulphinyl, C1-C3-alkylsulphonyl, phenyl, phenyl which is substituted by 1 to 3 radicals from the group comprising halogen, methyl, ethyl, methoxy, methylthio or nitro, or pyridyl, is reacted with hydrazine hydrate, and the resulting compound of the formula III <IMAGE> is subjected to acid hydrolysis. The compounds prepared according to the invention are suitable as starting materials for the preparation of effective pesticides.</p> |
