Patent ID: 8481744

Claim:
A process for producing an anthranilamide compound represented by formula (I) or its salt: wherein: R 1 is halogen, alkyl, haloalkyl, alkenyl, haloalkenyl, alkynyl, haloalkynyl, alkoxy, haloalkoxy, alkylcarbonyl, haloalkylcarbonyl, alkoxycarbonyl, haloalkoxycarbonyl, nitro, formyl or cyano; A is an alkyl group which is optionally substituted by Y; Y is a C 3-4 cycloalkyl group which is optionally substituted by at least one substituent selected from the group consisting of a halogen, an alkyl group and a haloalkyl group; and m is an integer of from 0 to 4, the process comprising: (i) reacting a compound represented by formula (II): wherein Z is a 2-pyridyl, a 3-pyridyl, a 4-pyridyl or a benzene substituted with a nitro group, with a brominating agent, to produce a compound represented by formula (III): and (ii) reacting the compound of the formula (III) with an oxidizing agent, to obtain the compound of formula (I).
