Methyl 4-(p-anilinophenoxy)butyrate prepared by the method of Example 1 was hydrolyzed in a mixture of aqueous potassium carbonate and N,N-dimethylformamide. The reaction mixture was acidified with hydrochloric acid and the solids precipitated thereby were collected and recrystallized from ethanol. The 4-(p-anilinophenoxy)butyric acid thus obtained was a greyish crystalline solid, m.p. 110°-111° C.
