Abstract (en)

[origin: WO9856764A1] The invention relates to a method for producing compounds of formula (I), wherein R1 = hydrogen or C1-C4-alkyl; R2 = hydrogen, C1-C6-alkyl, C3-C6-cycloalkyl or a CH2-B radical; A = an unsubstituted or mono or penta-substituted aromatic or non-aromatic monocyclic or bicyclic or heterocyclic radical and B = phenyl, 3-pyridyl or thiazolyl which are optionally substituted by one to three substituents, by hydrolyzing a compound of formula (II), wherein R1, R2 and A have the same meaning as in formula (I) and R3 stands for an unsubstituted or substituted C1-C10-alkyl, C3-C6-cycloalkyl, phenyl or benzyl. The invention is characterized in that the reaction is carried out at a pH value ranging from 7 to 14. The invention further relates to starting materials to implement said method. The compounds of formula (I) are suitable as intermediate products for the production of pesticide mixtures.
