Methyl 4-acetamido-5-chloro-2-methoxybenzoate is stirred with aqueous sodium hydroxide until complete solution is achieved. After filtration, concentrated hydrochloric acid is added, whereupon, the product precipitates out as a white solid which is filtered off, washed and dried. 4-Acetamido-5-chloro-2-methoxybenzoic acid is crystallised from isopropanol, filtered off, washed and dried.
