Ntxiv 2-furan formic acid rau hauv dej kom txias, do, thiab ntxiv bromine dropwise. Cov reactant tau rhuab thiab refluxed rau 0.5h. Tom qab txaus txias, txheeb xyuas cov khoom, lim, zom cov ncuav mog qab zib lim ua ke nrog sodium bisulfite chemicalbook thiab dej, thiab lim kom tau cov khoom nyoos. Cov khoom siv raw yog recrystallized nrog boiling dej thiab decolorized nrog activated carbon kom tau cov ntshiab 2,3-dibromo-2-butenoic acid. Tawm tswv yim 64-67%
