Synthetic Route of 288-36-8, 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.
Example 58:; N-[6-(3-MethyI-3H-[l,2,3]triazol-4-yl)-2,4-dioxo-7-trifluoromethyl-l,4-dihydro-2H- qninazoIin-3-yI]-methanesulfonamide; 1 -Methyl-1H-[1 ,2,3]triazole; To a solution of NaOMe (3.91 g, 72.4 mmol) in MeOH (50 mL) was added 1,2,3-lH-triazole (5 g, 72.4 mmol). The mixture was then cooled to 0 0C and MeI (4.53 mL, 72.4 mmol) was added dropwise. The mixture was stirred allowed to warm up to r.t. and stirred at this temperature for 2 h. The solvent was removed in vacuo, the residue was treated with hot toluene (40 mL) and then filtered to afford a yellow paste. This paste was slurried in hot CHCl3 and the solid was filtered off. The solid was washed with hot CHCl3 (2 X). The filtrates were combined, concentrated in vacuo and the residue distilled (112-116 0C, water pump) to afford a mixture of starting material and final product. The distillate was dissolved in THF and NaH was added portionwise. The insoluble material was filtered off, washed with Et2O and concentrated in vacuo to afford l-methyl-lH-[l,2,3]triazole (1.33 g, 22%) as a yellow syrup.
The synthetic route of 1H-1,2,3-Triazole has been constantly updated, and we look forward to future research findings.
