Synthetic Route of 1535-73-5,Some common heterocyclic compound, 1535-73-5, name is 3-Trifluoromethoxyaniline, molecular formula is C7H6F3NO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
(Formula 1-2: methyl 4-(((3-(trifluoromethoxy)phenyl)amino)methyl)benzoate)[1723][1724]Compound ofFormula 1-1(3-(trifluoromethoxy)aniline; 0.385 mL, 4.625 mmol), methyl 4-(bromomethyl)benzoate (1.271 g, 5.550 mmol) and DIPEA (1.228 mL, 6.937 mmol) were dissolved in acetonitrile (5 mL) at room temperature and stirred at the same temperature for 16 hours. Water was poured into the reaction mixture, and the organic layer was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution, dehydrated with anhydrous magnesium sulfate, filtered, and then concentrated under reduced pressure. The concentrate was purified and concentrated by column chromatography (silica; ethyl acetate/hexane=20percent) to give the desired compound ofFormula 1-2(0.607 g, 40.3percent) in the form of a white solid.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Trifluoromethoxyaniline, its application will become more common.
