With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.6344-72-5,6-Methylquinoxaline,as a common compound, the synthetic route is as follows.
6344-72-5, Example 242 : Synthesis of (1E,6E)-1-(4-hydroxyphenyl)-7-(quinoxalin-6-yl)hepta-1,6-diene-3,5-dione (CU348); (1) Synthesis of quinoxaline-6-carboxaldehyde; 6-Methylquinoxaline (500 mg, 3.47 mmol) and selenium dioxide (423 mg, 3.81 mmol) in a sealed vessel were stirred at 160C for 7 h. After cooled to room temperature, the reaction mixture was dissolved in ethyl acetate. The solution was washed with brine twice, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate = 80/20 to 60/40) to obtain the title compound as a pale brown solid (355 mg, 64%).
As the paragraph descriping shows that 6344-72-5 is playing an increasingly important role.
