Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline, A new synthetic method of this compound is introduced below., 6523-49-5
A mixture of the formamidine from step 1 (528 mg) and 4-triazolylaniline (294 mg) in AcOH (5 ml) was heated to 125 for 3 h. After cooling, the mixture was diluted and basified with IN NaOH (80 ml). The resulting cream ppt was isolated by filtration, and dried to give the title compound (495mg, 70%).1H NMR delta 10.3 (IH, br s), 9.34 (IH, s), 8.9 (IH, s), 8.67 (IH, s), 8.31 (IH, s),8.23 (IH, dd, J 8.85, 1.9Hz), 8.15 (2H, d, J 8.85Hz), 7.92 (4H, m), 7.19 (2H, d, J8.85Hz), 4.2 (2H, m), 2.72 (2H, m), 2.3 (6H, s); LC-MS rt 1.96 m/z 452 ES+.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
