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. 34486-24-3, name is 2-Amino-6-(trifluoromethyl)pyridine, the common compound, a new synthetic route is introduced below. Formula: C6H5F3N2

The 6 – (trifluoromethyl) pyridin -2 amine (972 mg, 6 . 0mmol) dissolved in chloroform (10 ml) in, cooling to 0 C, adding N-bromo succinimide (1.28g, 7 . 2mmol), stir at room temperature 3 hours, concentrated, crude product by silica gel column chromatography (petroleum ether: ethyl acetate = 2:1) purification, to obtain solid title compound (0.58g, yield 40.3%).

The synthetic route of 34486-24-3 has been constantly updated, and we look forward to future research findings.

Reference of 34486-24-3, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 34486-24-3 as follows.

To a solution of 6-trifluoromethyl-pyridin-2-ylamine (10.0 g, 62.1 mmol, 1 eq) in CHCI3 (200 mL) was added NBS (12.0 g, 67.4 mmol, 1.08 eq). The solution was stirred in the dark for 2 h, at which time it was added to DCM (200 mL) and 1 N NaOH (200 mL). Upon mixing, the layers were separated and the organic layer was dried and concentrated. The residue was purified by silica gel column (EA/PE = 1/1, v/v) to give 5-bromo-6- trifluoromethyl-pyridin-2-ylamine (6.5 g, 44%) as an orange solid.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,34486-24-3, its application will become more common.
