288-36-8, 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. 288-36-8, name is 1H-1,2,3-Triazole, A new synthetic method of this compound is introduced below.
a) (2-(2H-1.2.3-triazol-2-yl)phenyl)methanolTo a mixture of (2-iodophenyl)methanol (1 .50 g, 6.41 mmol), 1H-1,2,3-triazole (0.797 g, 11.54 mmol), frarts-N,N’-dimethylcyclohexane-1 ,2-diamine (0.091 g, 0.641 mmol) andCs2C03 (3.76 g, 11.54 mmol) in DMF (15 mL), Cul (0.61 g, 3.20 mmol) was added and the reaction mixture was stirred for 20 min at 120C and 15 min at 160C in the microwave. The reaction mixture was cooled to rt and filtered to remove the solids. The filtrate wasconcentrated under reduced pressure. The residue was purified by flash-columnchromatography over silicagel (eluent: gradient 10%- 100% ethyl acetate/heptane) to yield the title compound (1.46 g, 64%). [1H NMR (400 MHz, DMSO-d6) delta ppm 8.10 (s, 2 H), 7.74 (d, J=7.53 Hz, 1 H), 7.61 (dd, 8.03, 1.25 Hz, 1 H), 7.52 (td, J=7.53, 1.25 Hz, 1 H), 7.44 (m, 1 H), 5.26 (t, J=5.40 Hz, 1 H), 4.59 (d, J=5.02 Hz, 2 H); LCMS RtA = 0.68, [M+Hf = 176.1].
