Related Products of 6523-49-5, These common heterocyclic compound, 6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline, 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 mixture of formamidine from Step 1 (150 mg) and 4-triazolyl-aniline (88 mg, leq) in AcOH (2ml) was heated to 80 for 16 h. Cooled, concentrated and cautiously treated with sodium bicarbonate (aq). The resulting solid was isolated by filtration, washed with water then DCM:EtOH:NH3 (20:8:1) added and refiltered. The filtrate was concentrated until a precipitate formed which was filtered, washed with ether and dried to give the title compound (82 mg, 34 %). 1U NMR delta 10.0 (IH, s), 9.18 (IH, s), 8.75 (IH, s), 8.54 (IH, s), 8.12 (2H, m),7.97 (IH, m), 7.92 (2H, m), 7.78 (3H, m), 7.66 (IH, m), 7.53 (IH, m); LC-MS rt 2.52 m/z 401 ES+.
Statistics shows that 4-(1,2,4-Triazol-1-yl)aniline is playing an increasingly important role. we look forward to future research findings about 6523-49-5.
