Add 2-furan formic acid into water to cool, stir, and add bromine dropwise. The reactant was heated and refluxed for 0.5h. After sufficient cooling, analyze the product, filter, grind the filter cake together with sodium bisulfite chemicalbook and water, and then filter to get the crude product. The crude product was recrystallized with boiling water and decolorized with activated carbon to obtain pure 2,3-dibromo-2-butenoic acid. Yield 64-67%
