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.6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. name: 4-(1,2,4-Triazol-1-yl)aniline
[0342] A mixture of intermediate 33 (0.10 g, 0.28 mmol), 4-[l,2,4]triazol-l-yl- phenylamine (55 mg, 0.34 mmol), Pd2(dba)3 (25 mg, 0.027 mmol), Xantphos (30 mg, 0.052 mmol) and cesium carbonate (0.20 g, 0.61 mmol) in dioxane (3 mL) was sealed in a microwave reaction tube and irradiated with microwave at 160 C for 20 min. After cooling to room temperature, the cap was removed and the resulting mixture filtered. The filtered solid was washed with DCM, the filtrate concentrated and the residue purified by HPLC. The corrected fractions were combined and poured into saturated NaHCO3 solution (30 mL). The combined aqueous layers were extracted with EtOAc (2 x 30 mL) and the combined organic layers washed with brine, dried over anhydrous Na2SO4 and filtered. The filtrate was
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4-(1,2,4-Triazol-1-yl)aniline ,and how the biochemistry of the body works.
