Electric Literature of 689260-53-5, 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 689260-53-5 as follows.
2-Bromo-4-iodo1,3-xylene (10 mmol), 5,10-phenothiazine (10 mmol), Cu (20 mmol), under a nitrogen atmosphereK2CO3 (20 mmol) and N,N-dimethylformamide (20 ml) were combined to form a solution.The above mixed solution was evacuated three times with nitrogen, and heated and stirred at 130 C for 24 h. The reaction mixture was filtered through celite and usedWash with dichloromethane (20 ml).The solvent was evaporated under reduced pressure and purified by column chromatography (hexane/dichloromethane 10:1) to give the product 10-(4-bromo-3,5-dimethylphenyl)-phenothiazine S25-1 .
According to the analysis of related databases, 689260-53-5, the application of this compound in the production field has become more and more popular.
