Abstract£ºFour routes to the synthesis of bifenazate were screened. An efficient and scalable process was obtained starting from the methylation of 4-phenylphenol£¬followed by the reaction with diisopropyl azodicarcoxylate£¨DIAD£© under catalysis of a Lewis acid£¬and then selective decarboxylation. The structure of product was confirmed with 1H NMR.
