41253-21-8, The chemical industry reduces the impact on the environment during synthesis 41253-21-8, name is Sodium 1,2,4-triazol-1-ide, I believe this compound will play a more active role in future production and life.
1 g of a 1,2,4-triazole sodium salt was dissolved in N,N-dimethylformamide, and the solution was cooled to 0 C., to which 570 mg of 60% sodium hydride (NaH) was then added. The reactants were stirred for 20 min, and 1.3 mL of 1-bromo-3-chloropropane was slowly added thereto. The reaction mixture was warmed to room temperature and stirred for 12 hours, followed by addition of water and extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography to afford 600 mg (38%) of the title compound.1H NMR (CDCl3): delta 8.08 (s, 1H), 7.93 (s, 1H), 4.37-4.34 (m, 2H), 3.47-3.43 (m, 2H), and 2.35-2.29 (m, 2H)
