Related Products of 445-13-6, 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. 445-13-6, name is 3-Chloro-4-(trifluoromethyl)aniline belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a solution of 6 (0.13 mmol, 1 eq) in THF (0.5 mL, 0.26M) in a 1-dram vial at room temperature aniline/heterocyclic amine (0.13 mmol, 1 eq) was added in one portion. The vial was sealed and the mixture heated to reflux for 16 hours to yield crude 7. For compounds 8, after cooling to room temperature, N,N-Diisopropylethylamine (0.143 mmol, 1.1 eq) and isobutyl chloroformate (0.143 mmol, 1.1 eq) were added and the reaction was stirred for 30 minutes at room temperature. For primary carboxamide congeners, ammonium hydroxide (1mL) was added and the reaction was stirred for an additional hour at room temperature. For substituted amide analogs, desired amine (0.26, 2 eq) was added instead of ammonium hydroxide and stirring was continued for an additional 2 hours. The reaction was then diluted with ether (1mL), the layers were separated and the aqueous layer was extracted with ether (3x2mL). The organic layers were passed through a phase separator and concentrated in vacuo, and then crude product was purified using preparative HPLC (30x50mm column, MeCN/0.1% TFA: Water, 4 min gradient) to yield desired compounds 8.
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-Chloro-4-(trifluoromethyl)aniline, other downstream synthetic routes, hurry up and to see.
