With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1593-08-4,2-Formylquinoxaline,as a common compound, the synthetic route is as follows.
Weighing 2.2mmol (0.348g) quinoxaline-2- formaldehyde in 100 ml flask in three adding proper amount of anhydrous ethanol, heating to reflux, using a 100 ml beaker weighing 1mmol (0.227g) N-ethyl -3,6-diamino-carbazole, adding an amount of ethanol and heating, the in-by-drop in the flask, will soon have the yellow flocculent solid precipitated, the drop finishes, continue to reflux reaction 5h. After the reaction, to take advantage of heat filtering, product a plurality of times with hot ethanol washing, drying, obtain raphide 0.43 g. In accordance with the aforesaid containing structural unit and diphenylenimine quinozaline the molecular structure of the target derivative., 1593-08-4
The synthetic route of 1593-08-4 has been constantly updated, and we look forward to future research findings.
