Production methodprocess: Gallic acid was esterified with methanol catalyzed by sulfuric acid to produce methyl 3,4, 5-trihydroxybenzoate, and then methylated with dimethyl sulfate to obtain methyl 3-methoxy-4, 5-chemicalbook dihydroxybenzoate, which was then condensed with diiodomethane under basic conditions to produce methyl 5-methoxy-3, 4-dioxy-methylene benzoate. Finally, the product was prepared by bromination.
