Synthetic Route of 886762-08-9, The chemical industry reduces the impact on the environment during synthesis 886762-08-9, name is 5-Bromo-2-(trifluoromethoxy)aniline, I believe this compound will play a more active role in future production and life.
General procedure: 1,1-Cyclopropanedicarboxylic acid (5) (12.0 g, 15.4 mmol) was dissolved in anhydrous THF (50 mL). Then triethanolamine (2.0 mL,13.9 mmol) was added to the mixture and the mixture was stirred on the ice-bath for 30 min. SOCl2 (1.2 mL, 16.66 mmol) was then added. Stirring was continued for 2h, a solution of 3,5-dimethylaniline 6 (3.6 g, 15.4 mmol) in anhydrous THF (10 mL) was added and continued stirring for 2h, after that, the ice bath was removed, and the mixture was stirred at room temperature overnight. After the completion of the reaction, the mixture was filtered and concentrated in vacuo. The residues was purified by silica gel flash chromatography (PE/AcOEt = 5:1) to yield 7 as white solid (0.8 g, 30.7%).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5-Bromo-2-(trifluoromethoxy)aniline, other downstream synthetic routes, hurry up and to see.
