First take an appropriate amount of 2-hydroxy-3,4,5,6-tetrachlorobenzoic acid and 4-iodoresorcinol as starting materials and place them in a clean reactor. Using an appropriate amount of concentrated sulfuric acid as a catalyst, add a certain amount of glacial acetic acid as a solvent to ensure that the raw materials can be fully dispersed in it. Heat up to a specific temperature range, usually about 100-120 ° C, and continue to stir the reaction at this temperature to make the two fully condensed. During the reaction, close attention should be paid to the reaction process, which can be monitored by thin-layer chromatography (TLC) to determine the end point of the reaction.

When the reaction is completed, cool the reaction mixture to room temperature, and then slowly pour it into a large amount of ice water to promote the precipitation of the product. Use a Brinell funnel for suction filtration to collect the precipitated solid crude product. Next, an appropriate amount of ethanol-water mixed solution is used to recrystallize the crude product to remove impurities and improve the purity of the product. After several recrystallization, relatively pure 4,5,6,7-tetrachloro-2 ', 4', 5 ', 7' -tetraiodine-3-oxo-3H-spiro [2-benzofuran-1,9 '-ton] -3', 6 '-diol can be obtained.
