New discoveries in chemical research and development in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world.288-36-8, name is 1H-1,2,3-Triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 288-36-8
To a solution of 2-fluoro-6-iodobenzoic acid (502.5 mg), copper(I) iodide (36.5 mg), cesium carbonate (1.25 g) and trans-N,N’-dimethylcyclohexane-1,2-diamine (0.047 mL) in N,N-dimethylformamide (2.0 mL) was added 1H-1,2,3-triazole (330.3 mg), and the mixture was stirred at 100 C. for 0.5 hr. To the reaction mixture were added ethyl acetate and water. The obtained aqueous layer was neutralized with 1N aqueous hydrogen chloride solution, and extracted with ethyl acetate. The obtained organic layer was washed successively with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (445.6 mg). MS: [M+H]+ 208.1.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1H-1,2,3-Triazole ,and how the biochemistry of the body works.
