摘要:The present disclosure relates to a benzimidazole-substituted phenyl-n-butyramide-based compound and the preparation method thereof. The method of the present disclosure avoids nitration reaction and polyphosphoric acid cyclization reaction, and avoids the generation of a large amount of waste acid reaction solution from the source. The synthesis method embodied in the invention has the advantages of simplicity and high efficiency, mild conditions and few pollutants, etc., and is suitable to be developed as a green and sustainable production process.
