Research on new synthetic routes about 5-Bromo-2-iodobenzoic acid

According to the analysis of related databases, 21740-00-1, the application of this compound in the production field has become more and more popular.

Reference of 21740-00-1, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 21740-00-1 as follows.

General procedure: A mixture of 2-iodobenzoic 1a (0.2 mmol), acetylacetone 2a (0.4 mmol), and Cs2CO3 (65.2 mg, 0.20 mmol) in CH3CN was stirred at 100 C. When the reaction was considered complete as determined by TLC analysis, the reaction was allowed to cool to room temperature and quenched by water, and the mixture was extracted with CH2Cl2. The combined organic extracts were washed with water and saturated brine. The organic layers were dried over Na2SO4, filtered. Solvents were evaporated under reduced pressure. The residue was purified by chromatography on silica gel to afford isocoumarins derivatives and isoquinolone derivatives.

According to the analysis of related databases, 21740-00-1, the application of this compound in the production field has become more and more popular.
