Paragraph 0011; 0015; 0016, (2021/03/11)
The invention discloses a synthesis method of 7-bromo-5-methoxyquinoline, which comprises the following steps: carrying out Skraup condensation reaction on 3, 5-dibromoaniline serving as a raw material and glycerol to obtain 5, 7-dibromoquinoline, reacting with sodium methoxide to obtain 5-bromo-7-methoxyquinoline and 7-bromo-5-methoxyquinoline, and finally carrying out column chromatography purification and separation to obtain the 7-bromo-5-methoxyquinoline. The method overcomes the defects of low yield, microwave condition requirement, difficulty in post-treatment, difficulty in amplification and the like in the existing synthesis process. According to the synthetic method, the 3, 5-dibromoaniline is used as a raw material, the process selection is reasonable, the raw material cost is low, the raw materials are simple and easy to obtain, the operation and post-treatment are convenient, the total yield is high, a highly toxic reagent is not used, amplification is easy, and large-scale production can be carried out.
