Procedure

A mixture of 50 parts of 2-amino-3,5-dichlorobenzoic acid and 240 parts of ethanol is saturated with gaseous hydrogen chloride. The whole is stirred and refluxed for 10 hours. The reaction mixture is allowed to cool and the solvent is evaporated. To the solid residue are added water and sodium hydroxide. The precipitated product is filtered off and dried, yielding 25 parts of ethyl 2-amino-3,5-dichlorobenzoate.
