Procedure

To a mixture of 30 ml of 4% potassium hydroxide solution and 30 ml of methanol was added 2 g of ethyl 5-cyano-2-hydroxyoxanilate and the mixture was stirred overnight at room temperature. To the reaction mixture was added 15 ml of 10% hydrochloric acid solution and white crystals formed were recovered by filtration and recrystallized from water to provide 1.2 g of 5-cyano-2-hydroxyoxanilic acid.
