With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.148231-12-3,5,8-Dibromoquinoxaline,as a common compound, the synthetic route is as follows.
In N2in the gas purification system, the carbazole is dissolved in 1,4-dioxane solvent, and by adding CuI and K3PO4. Add another 5,8- […][…] (1.1 equivalent) and trans -1,2-diamino cyclohexane. In the solution 110 C and the temperature of the refluxing under stirring 24 hours. After the completion of reaction, to the room temperature and cooling the solution and distilled water extraction by ethyl acetate. From the extraction of using magnesium sulphate remove the moisture in the organic layer, and removing the remaining organic solvent. The material through the use of hexane and ethyl acetate to carry out wet refining column chromatography, thereby obtaining compound “l”. (Yield: 48%)
148231-12-3, The synthetic route of 148231-12-3 has been constantly updated, and we look forward to future research findings.
