FIELD: chemistry.

SUBSTANCE: invention relates to a compound of formula (X), which can be used in preparing a herbicide. In formula (X), ring A is A¹ or A², R^B2 is selected from a group consisting of methyl, ethyl, n-propyl, trifluoromethyl and difluoroethyl, R^B3SN is chlorine, fluorine, bromine, methyl, ethyl, difluoromethyl, trifluoromethyl, C₁-C₃haloalkoxy or C₁-C₃alkoxy, the broken line denotes a point of attachment to the rest of the compound of formula (X), each of R^Q1 and R^Q4 is hydrogen, R^Q2 and R^Q3 together with carbon atoms to which they are attached form a ring Q, where ring Q is Q1 or Q2, where R¹ is methyl, "a" denotes a point of attachment to ring A, and "c" denotes a point of attachment to a carboxylate fragment. Invention also relates to a method of producing a compound of formula (X), use thereof in the manufacture of a herbicide and a compound of formula (E), in which ring A is A¹ or A², R^B2 is C₁-C₃alkyl or C₁-C₃fluoroalkyl; R^B3SN is chlorine, fluorine, bromine, methyl, ethyl, difluoromethyl, trifluoromethyl, C₁-C₃haloalkoxy or C₁-C₃alkoxy; broken line denotes a point of attachment to the rest of the compound of formula (E) and R¹ is methyl.

EFFECT: compounds of the present invention can be used in the preparation of an herbicide.
