In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 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. Computed Properties of C2H3N3
To a mixture of the product from step 2 (7.9 g, 38 mmol), Cs2CO3 (24.8 g,76 mmoi) and Ciii (2.88 g, 7.6 mmoi) in DMF (200 mL) were added 2H-[i,2,3]triazoie (5.24 g,76 mmoi) andN,N-.dimethyi-cyciohexanei,2diamine (0.9 g, 6.5 mmol) and the mixture was slirred at 110C overnight. The cooling mixture was adjusted to pi-ii2 with IM sodium hydroxide and extracted with EtOAc (50 rnL x 3). The aqueous layer was adjusted to pH 4 with 1M HC1 and extracted with EtOAc (50 mLx4). The extracts was dried over NaSO4, filtered, the filtrate concentrated in vacuo and the residue purified by chromatography on silica (Petroleum ether : EtOAc =10:1) toprovide the title compound (4.1 g). LRMS rnlz (M+H) 196,0 found, 196,0 required.
The synthetic route of 288-36-8 has been constantly updated, and we look forward to future research findings.
