Application 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.
A) (3-Trifluoromethoxy-phenylamino)-acetonitrile; A mixture of 3-(trifluoromethoxy)aniline (1.00 g, 5.64 mmol), bromoacetonitrile (745 mg, 6.21 mmol), sodium iodide (1.86 g, 12.4 mmol), and sodium carbonate (858 mg, 6.21 mmol) in CH3CN (15 mL) was heated at reflux for 18 h, then partitioned between water and EtOAc. The organic layer was washed with brine, dried (MgSO4), filtered, and evaporated. Chromatography (SiO2; heptane/EtOAc gradient) afforded the title compound (904 mg, 74percent). Brown liquid, MS: 215.2 (M+H)+.
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.
