Application of 454-79-5, 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 454-79-5 as follows.
Under ice-cooling, 2.6 mL of diethyldisulfide was dropped to a mixture of 5.0 g of 2-bromo-5- (trifluoromethyl) aniline, 2.77 mL of isoamyl nitrite and 50 mL of acetonitrile. The reaction mixture was stirred at 50 C. for 6 hours. The reaction mixture was allowed to cool to room temperature, water was added and extracted with ethyl acetate. The obtained organic layer was washed with saturated brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was subjected to silica gel chromatography to obtain 4.5 g of Intermediate 1-13 shown below.
According to the analysis of related databases, 454-79-5, the application of this compound in the production field has become more and more popular.
