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.202931-88-2, name is 1-Methyl-1H-1,2,3-triazole-5-carbaldehyde belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Safety of 1-Methyl-1H-1,2,3-triazole-5-carbaldehyde
6-bromo-4-chloro-2-methoxy-3 – (4 – (trifluoromethyl) benzyl) quinoline (1.45 g, 3.37 mmol, Intermediate 10: step d) comprises that the flask, THF (25 was added to mL), the solution was cooled to -75 .n-BuLi (dropwise 2.5 M, 1.3 mL, 3.25 mmol )in hexane.After 2 minutes, 3 mL of THF 1 -methyl -1H-1,2,3-triazole-5-carbaldehyde (580 mg, 5.22 mmol, Intermediate 18) was introduced.The reaction mixture was warmed to -20 over 45 minutes and, at this time the reaction NH4was quenched with aqueous solution of Cl.Extract the aqueous portion with EtOAc (5 × 40 mL), washing the combined organics with brine, MgSO4dried over, filtered and concentrated.Silica gel (5% CH3CN-DCM, 30% CH3by chromatography on increased to CN + 2% MeOH), to give the title compound as a pale yellow non-crystalline solid.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1-Methyl-1H-1,2,3-triazole-5-carbaldehyde ,and how the biochemistry of the body works.
