Related Products of 6523-49-5,Some common heterocyclic compound, 6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline, molecular formula is C8H8N4, 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 forniamidine from Step 1 (200 mg) and 4-triazolyl-aniline(112 mg, 1 eq) in AcOH (2 ml) 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 (129mg, 47%).1H NMR delta 10.06 (IH, s), 9.29 (IH, s), 8.81 (IH, s), 8.63 (IH, s), 8.23 (2H, m),8.07 (2H, d, J 10.0Hz), 7.93 (IH, s), 7.88 (2H, m), 7.83 (IH, m), 7.73 (IH, d, J7.50Hz), 7.35 (IH, t, J 8.75Hz), 3.92 (3H, s); LC-MS rt 2.42 m/z 413 ES+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-(1,2,4-Triazol-1-yl)aniline, its application will become more common.
