YieldReaction ConditionsOperation in experiment
50% With hydrogenchloride; sulfuric acid; sodium nitrite; In ethanol; water; at 0 - 100℃; for 13.5h; 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 3x100 mL of ethyl acetate and the organic layers combined. The resulting mixture was washed with 3x50 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].
With hydrogenchloride; conc. sulphuric acid; sodium nitrite; In ethanol; water; b) 5-Bromo-2-trifluoromethoxyphenol A solution of 210 mmol of sodium nitrite in 120 ml of water is added dropwise to a suspension of 200 mmol of <strong>[886762-08-9]5-bromo-2-trifluoromethoxyaniline</strong> in 500 ml of ethanol and 50 ml of conc. HCl at 0C. The reaction mixture is stirred at 5C for 1.5 hours. The reaction mixture is slowly added dropwise to a solution of 135 ml of conc. sulphuric acid in 2.8 l of water and stirred under reflux overnight. The reaction mixture is extracted with diethyl ether (3x) - the combined organic phases are washed with water and 1 M sodium bicarbonate solution and then extracted with 2N NaOH (2x). The combined aqueous phases are acidified with conc. HCl and extracted with diethyl ether (3x). The combined organic phases are washed with water, dried with sodium sulphate and evaporated. The crude title compound is obtained from the residue.
