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 886762-08-9 as follows. name: 5-Bromo-2-(trifluoromethoxy)aniline
10.74 g (93.75 mmol) of tert-butyl nitrite and 28.5 g (150 mmol) of copper iodide are suspended in 270 ml of acetonitrile and heated to 60 C. A solution of 15 g (62.5 mmol) of 5-bromo-2-trifluoromethoxyaniline in 130 ml of acetonitrile is slowly added dropwise to this suspension and the mixture is left to stir at 60 C. for another hour. The reaction solution is then poured on to a mixture of 250 ml of 2 N aqueous HCl and 250 ml of ethyl acetate. The organic phase is washed twice more with aqueous NaCl solution, filtered through a little silica gel and concentrated. The residue is separated by chromatography on silica gel (ethyl acetate/n-heptane=1/18). This affords 12.2 g (52% yield) of product 96 as a colorless oil.
According to the analysis of related databases, 886762-08-9, the application of this compound in the production field has become more and more popular.
