Reaction Steps

A mixture of 1.1 g of bromine and 5 ml of acetic acid was added dropwise to a solution of 1.5 g of ethyl 5-cyano-2-hydroxyoxanilate and 1 g of sodium acetate in a mixed solution of 10 ml of dimethyl sulfoxide, 10 ml of methanol and 20 ml of acetic acid. After stirring the mixture for 30 minutes at room temperature, 6 ml of 2 normal hydrochloric acid and 200 ml of water were added to the reaction mixture and the product was extracted with a mixture of 30 ml of toluene and 40 ml of ethyl acetate. The extract was washed with water, dried, and then concentrated under reduced pressure. Crystals formed were washed with a mixture of ether and n-hexane to provide 1.5 g of ethyl 3-bromo-5-cyano-2-hydroxyoxanilate.
