Research speed reading in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 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. category: Triazoles
Example 11Preparation of N-f2-U-?5′,2lS)-2-[-l-(‘5-chloropyrimidin-2-yl)piperidiri-4-yl]cycIopropyllethyl)-4- (IH-1.2,4-triazol- 1 -vnaniline.Step 1: fcrt-butyl [4-(lH-1,2,4-triazol-1-vDphenyl]carbamate.4-(lH-1,2,4-triazol-1-yl)aniline (250mg, 1.51mmol) and di-tert-butyl dicarbonate (409mg, 1.82mmol) were added in toluene (7.6mL). The reaction was heated to 70C for over the weekend. The reaction was cooled to room temperature, concentrated and purified by column chromatography through a 50 gram Biotage SNAP KP-Sil silica gel cartridge eluting with 50% ethyl acetate/hexanes to give the title compound as a white solid.LRMS calc: 260.29; obs: 160.92 (M-IOO).
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 6523-49-5
