Process for preparing 3-chloroanthranilic alkyl esters by reacting 3-chloroanthranilic acid, in an inert solvent, with from 0.8 to 5 parts by weight of phosgene, and reacting the 3-chloroisatoic anhydride which is formed with an alkanol, where appropriate in the presence of an esterification catalyst, to give the 3-chloroanthranilic alkyl ester.
