A new synthetic route of 1H-1,2,3-Triazole

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, 1H-1,2,3-Triazole, other downstream synthetic routes, hurry up and to see.

Adding a certain compound to certain chemical reactions, such as: 288-36-8, name is 1H-1,2,3-Triazole, belongs to Triazoles compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 288-36-8, 288-36-8

To a mixture of the product from step 2 (7.9 g, 38 mmol), cesium carbonate (24.8 g,76 mmol) and Cul (2.88 g, 7.6 mmol) in DMF (200 mL) were added 2H-[1,2,3]triazole (5.24 g,76 mmol) and N,N’-dimethyl-cyclohexane-l12-diamine (0.9 g, 6.5 mmol) and the mixture was heated to 110C overnight. The cooled reaction mixture was adjusted to ~pH 12 with 1M sodium hydroxide and extracted with EtOAc (50 mL x 3). The aqueous layer was adjusted to ~pH 4 with 1M HCl and extracted with EtOAc (50 mLx4). The extracts was dried over Na2SO4, filtered, the filtrate concentrated in vacuo and the residue purified by chromatography on silica (petroleum ether : EtOAc =10:1) to provide the title compound. LRMS m/z (M+H) 196.0 found, 196.0 required.
