Procedure

Ethyl 3-(phenylamino)benzoate (0.175 g; 0.725 mmol) was added to a mixture of NaOH in water (1 mL; 2M) and dioxane (1 mL) and stirred vigorously at room temperature overnight. The resulting mixture was concentrated in vacuo and extracted with dichloromethane. The aqueous layer was acidified with a 6N solution of hydrochloric acid in water. The precipitated product was collected by filtration to yield 0.155 g (quantitative) of the title compound as a grey solid which was used without further purification.
