Reaction Steps

To 5-bromosalicylic acid (25 g, 115 mmol) in ethyl alcohol (300 mL) was added sulfuric acid (98%, 2 mL). The mixture was refluxed in a Dean-Stark apparatus for 2 days. The reaction mixture was cooled to room temperature. Most of the ethyl alcohol was removed by distillation. The residue was diluted with ethyl acetate, washed with water, aq. Na2CO3 and brine. The organic layer was dried (Na2SO4) and the solvent was removed to afford the title compound as a white solid.
