Electric Literature of 815588-93-3, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 815588-93-3, name is 1-Methyl-1H-1,2,4-triazole-5-carboxylic acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A mixture of 1 -methyl-1 H-1 ,2,4-triazole-5-carboxylic acid (7.0 g, 55.1 mmol) in SOCI2 (20 mL) was heated to 70 °C for 2 h. The mixture was concentrated to dryness. The residue was dissolved in Nh /MeOH (7M, 40 mL) and stirred at rt overnight. The precipitated solid was filtered off, extracted with Et20 and dried under reduced pressure to give the title compound
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 815588-93-3.
