Related Products of 41253-21-8, These common heterocyclic compound, 41253-21-8, name is Sodium 1,2,4-triazol-1-ide, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A suspension of 2-fluorobenzylnitrile (3.0 g, 25 mmol) and 1,2,4-triazole sodium salt (2.4 g, 27 mmol) were stirred in tetrahydrofuran (7 mL) and dimethylformamide (14 mL) at 95 C. for 18 h. After cooling and concentrating, the product was crystallized from hot CH2Cl2/hexane (1:1) to give the title compound as a white solid (4.25 g, 100% yield). 1H-NMR (300 MHz, CDCl3) delta ppm: 8.74 (1H, s), 8.16 (1H, s), 7.82 (1H, dd, J=4.9,1.3 Hz), 7.77-7.25 (2H, m), 7.57-7.51 (1H, m). LCMS [M+H]+ calcd for C9H7N4: 171.06; found: 171.12.
Statistics shows that Sodium 1,2,4-triazol-1-ide is playing an increasingly important role. we look forward to future research findings about 41253-21-8.
