Related Products of 175278-17-8, These common heterocyclic compound, 175278-17-8, name is 2-Bromo-4-(trifluoromethoxy)aniline, its 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.
General procedure: Triphosgene (0.09 g, 0.3 mmol) was dissolved in anhydrous CH2Cl2 (15 mL) and the mixture was stirred on the ice-bath for 15 min. 3-Bromo-5-(trifluoromethyl)aniline (0.16 g, 0.7 mmol) in anhydrous CH2Cl2 (10 mL) was added dropwise to the above mixture and stirring continued for 20 min. Et3N (0.12 mL, 0.89 mmol) diluted with CH2Cl2 (5 mL) was then added into the mixture. Stirring was continued for 20 min and a solution of Et3N (0.12 mL, 0.89 mmol), compound (9) (0.2 g, 0.74 mmol) in anhydrous CH2Cl2 (20 mL) was added. After completion of the action, the reaction was quenched with dilute Na2CO3. The organic layer was washed with water and brine, and dried over Na2SO4. After filtration and concentration in vacuo, the residues was purified by silica gel flash chromatography (PE/AcOEt = 3:1) yielding (W1).
The synthetic route of 175278-17-8 has been constantly updated, and we look forward to future research findings.
