New downstream synthetic route of 6523-49-5

The synthetic route of 6523-49-5 has been constantly updated, and we look forward to future research findings.

In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. HPLC of Formula: C8H8N4

A mixture of formamidine from Step 3 (594 mg) and 4-triazolyl-aniline(279 mg, 1 eq) in AcOH (6 ml) was heated to 125 for 2 h. On cooling and dilution with water (20 ml), a yellow precipitate was isolated by filtration, slurried with IN NaOH and washed with water. After drying, this material was triturated with MeOH / water/ acetone ~ 10:5:5 to give, after filtration and drying, a pale cream solid (510mg, 64%).1H NMR delta 10.1 (IH, br s), 9.27(1H, s), 8.8 (IH, s), 8.58 (IH, s), 8.24(1H, s), 8.18 (IH, d, J 8.85Hz), 8.03 (2H, d, J8.85Hz), 7.84 (4H, m), 7.68 (IH5 d, J9.5Hz), 7.35 (IH, t, J 8.85Hz), 4.26 (2H, m), 3.72 (2H, m), 3.35 (3H, obscured by H2O); LC-MS rt 2.4 m/z 457 ES+.

The synthetic route of 6523-49-5 has been constantly updated, and we look forward to future research findings.
