A mixture of ethyl 2-[2-amino-3-(2,3-dichlorophenoxy)phenyl]acetate (3.7 g.), sodium hydroxide (880 mg.) and water (50 ml.) was treated in a similar manner to that of Example 5-(2). The resultant residue was pulverized with benzene, and the precipitates were collected by filtration and dried to give 2-[2-amino-3-(2,3-dichlorophenoxy)phenyl]acetic acid (2.65 g.).
