Application of 54962-75-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 54962-75-3, name is 3-Bromo-5-(trifluoromethyl)aniline belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a solution of 3-bromo-5-(trifluoromethyl)aniline (10 g) in pyridine (50 mL) was added acetic anhydride (5.6 g) at 0 C., and the mixture was stirred at room temperature for 16 hr. The reaction mixture was concentrated, 1M hydrochloric acid was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with 1M hydrochloric acid, saturated aqueous sodium hydrogencarbonate solution, and saturated brine, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated to give the title compound (12.9 g, yield quant.) as a white solid.1H-NMR (300 MHz, CDCl3) delta: 2.21 (s, 3H), 7.36 (br. s, 1H), 7.49 (s, 1 H), 7.68 (s, 1H), 7.99 (s, 1H).
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, 3-Bromo-5-(trifluoromethyl)aniline, other downstream synthetic routes, hurry up and to see.
