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. category: ethers-buliding-blocks
Into a 250-mL 3-necked round-bottom flask, was placed 5-bromo-2- (trifluoromethoxy) aniline (2 g, 7.81 mmol, 1 equiv), ethanol (20 mL), HCl (2 mL). This was followed by the addition of NaN02 (595 mg, 8.62 mmol, 1.10 equiv) dropwise with stirring at 0 C. To this was added water (110 mL), sulfuric acid (5.5 mL). The resulting solution was stirred for 1.5 h at 0 C in a water/ice bath. The resulting solution was allowed to react, with stirring, for an additional 12 h while the temperature was maintained at 100 C in an oil bath. The resulting solution was extracted with 3×100 mL of ethyl acetate and the organic layers combined. The resulting mixture was washed with 3×50 mL of sodium bicarbonate. The mixture was dried over anhydrous sodium sulfate. This resulted in 1 g (50%) of the title compound as an oil. Analytical Data: LC-MS: (ES, m/z): RT =1.715min, LCMS 53: m/z = 257 [M+l].
