Application of 112671-42-8, 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 112671-42-8 as follows.
Under nitrogen conditions, 7H-dibenzo[c,g]carbazole (12.8 g, 47.8 mmol),4-bromo-1-iodo-2-nitrobenzene (17.2 g, 52.6 mmol), cesium carbonate (13.8 g, 71.7 mmol) was stirred in a solvent of dimethyl sulfoxide. After stirring at room temperature for about 2 hours, Raise the temperature to 60 C and stir for 8 hours. Extracted three times with dichloromethane and deionized water, after rotary evaporation, dry over anhydrous MgSO4 and recrystallize the compound from dichloromethane/methanol.Intermediate 1-1 (19 g, 85%) was obtained.
According to the analysis of related databases, 112671-42-8, the application of this compound in the production field has become more and more popular.
