titleOfInvention Method for preparing biphenyl compound
abstract Belonging to field of pharmaceutical chemistry, the invention relates to a method for preparing biphenyl compound. The preparation method comprises the following steps: dissolving a raw material in water solution composed of organic solvent and alkaline; then adding reducing agent into the mixture in batches for carrying out debromination reaction; after completion of the reaction, carrying out standing layering and concentration on the mixture at room temperature to obtain the compound with a formula I; wherein the raw material is a compound with a structural formula II or biphenyl compound crude product recovered from crystallized mother liquor obtained by brominating the compound with the formula I.
