Abstract
To study the synthesis of methyl 2-bromo-3,4-methylenedioxy-5-methoxybenzoate(the intermediante of bifendate)with bromination after cyclization,the compound was synthesized through methanol-esterification,methyl etherification,cyclization of methylene chloride,bromination by Gallic acid as raw material with a total yield of about 37 %,and was structurally corroborated by IR and 1HNMR.The synthesis is feasible in production.
