-
Paragraph 0078-0083, (2021/07/17)
The invention discloses a synthesis method of a 2,4-dichloroquinoline compound, belonging to the technical field of organic synthesis. The method comprises the following steps: at room temperature, mixing triphosgene and triphenylphosphine oxide, dissolving the mixture in an organic solvent, stirring for 10-30 minutes, adding an alpha-substituted acetyl arylamine compound, heating the reaction system to 90-130 DEG C, continuously stirring and reacting for 3-6 hours, and post-treating the obtained reaction liquid to obtain the 2,4-dichloroquinoline compound. The method for synthesizing the 2, 4-dichloroquinoline compound has the advantages of few steps, high yield and safer and more convenient operation; meanwhile, the triphenylphosphine oxide used in the reaction can be recycled, so that the emission of phosphorus-containing wastes is greatly reduced, and the method is suitable for industrial production.
