Summary:A process for the preparation of aminotriazine derivatives of the formu la (see formula I) wherein R is hydrogen, C1-C6alkyl, C3-C6cycloalkyl, C1-C4alkyl substituted by from 1 to 10 halogen atoms or by from 1 to 3 radicals from the group C1-C3alkoxy, C1- C3alkylthio and phenyl, phenyl or phenyl substituted by from 1 to 3 radicals from the group halogen, methyl, ethyl, methoxy, methylthio and nitro, which process comprises reacti ng with hydrazine hydrate a compound of formula II (see formula II) wherein R1 is hydrogen, C1-C4alkyl, C3-C6cycloalkyl, C1-C4alkyl substituted by from 1 to 9 chlorine atoms, C1-C3alkoxy, C1-C3alkylthio, C1-C3alkylsulfinyl, C1- C3alkylsulfonyl, phenyl, phenyl substituted by from 1 to 3 radicals from the group halogen, methyl, ethyl, methoxy, methylthio and nitro, or pyridyl, and subjecting the resulting compound of formula III (see formula III) to acid hydrolysis. The compounds prepared in accordance with the invention are suitable as starting materials for the preparation of effective pesticides.
