Research speed reading in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 217448-86-7, name is Methyl 1-(2,6-difluorobenzyl)-1H-1,2,3-triazole-4-carboxylate belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 217448-86-7
In a 250 ml round bottom flask, 2,6-difluorobenzylbromide (0.024 mol, 5 g), sodium azide (0.026 mol, 1.72 g) and water (50 ml) were added. The reaction mixture was heated to 700C to 750C for 30 hours and formation of the azide intermediate was monitored by thin layer chromatography (TLC). After the completion of reaction, the reaction contents were cooled to room temperature and then to this methyl propiolate (0.024 mol, 2.1 ml) was added dropwise, maintaining the contents at room temperature. On complete addition, the mixture was again heated at 600C to 650C for 4 to 5 hours. After the reaction was completed, the contents were cooled to room temperature and to this 25% aqueous ammonia (40 ml) solution was added dropwise. The reaction contents were heated to 700C to 750C for 4 to 5 hours and then gradually cooled to room temperature. The solid obtained was filtered and washed with water. The product was dried under vacuum at 700C – 750C to give 3.0 g of rufinamide.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 217448-86-7, and we look forward to future research findings.
