Method for producing high-purity alkyl ester of 3-chloroanthranilic acid from 3-chloroanthranilic acid |
| abstract |
(57) [Abstract] [Purpose] 3-chloroanthranilic acid was used to produce high-purity 3- A method for producing an alkyl chloroanthranilic acid ester. Composition: 3-chloroanthranilic acid is reacted with 0.8 to 5 parts by weight of phosgene in an inert solvent, and the resulting 3-chloroisatoic anhydride is reacted with an alkanol, optionally in the presence of an esterification catalyst. At least 3- An alkyl ester of chloroanthranilic acid is obtained. |
