Adding a certain compound to certain chemical reactions, such as: 454-79-5, name is 2-Bromo-5-(trifluoromethyl)aniline, belongs to bromides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 454-79-5, category: bromides-buliding-blocks
70% Sulfuric acid (18 mL) was added drop-wise to the solution of 2-bromo-5- (trifluoromethyl)aniline (5.0 g, 21.0 mmol, 1.0 eq), propane- 1, 2,3 -triol (3.8 g, 42.0 mmol, 2.0 eq) and sodium m-Nitrobenzene sulfonate (7.3 g, 32.55 mmol, 1.55 eq) at 0 C and the mixture was stirred under nitrogen atmosphere, at 150 C for 4 h. After complete consumption of starting material, the mixture was cooled to ambient temperature, poured into chilled water and filtered through a celite bed. The filtrate was neutralized with 2N aqueous NaOH, which led to a precipitate, which was filtered and dried under vacuum to obtain 8-bromo-5- (trifluoromethyl)quinoline. LCMS: Purity 95.13%. MS calculated for [M] 274.96 and found [M+H] +276.04.
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, 2-Bromo-5-(trifluoromethyl)aniline, other downstream synthetic routes, hurry up and to see.
