Related Products of 3179-31-5, 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. 3179-31-5, name is 1H-1,2,4-Triazole-3-thiol belongs to Triazoles compound, it is a common compound, a new synthetic route is introduced below.
Step A–Cyclohexylmethyl 1,2,4-Triazol-3-yl Sulfide Cyclohexylmethyl bromide (42 ml; 0.30 mol) was added over 5 min to 1,2,4-triazole-3-thiol (30.3 g; 0.30 mol) and sodium methoxide (17.3 g; 0.32 mol) in dry methanol (250 ml) under dry nitrogen. The mixture was refluxed for 4 h, stirred at room temperature overnight and evaporated. The residue was dissolved in ethyl acetate (400 ml) and water (200 ml). The organic phase is separated, washed with water (100 ml), dried (Na2 SO4), filtered and its volume reduced by evaporation, causing a solid to precipitate. The solid was filtered off and dried, to afford cyclohexylmethyl 1,2,4-triazol-3-yl sulfide (48.0 g; 81%) as white plates, m.p. 74-78 C. (Found, C: 54.98; H: 7.85; N: 21.32; S: 16.13. C9 H15 N3 S requires C: 54.79; H: 7.66; N: 21.30; S: 16.25%). NMR – d(CDCl3; 90 MHz) 0.50-2.10 (11H, m), 3.1 (2H, d, J=6.4 Hz), 8.13 (1H, s) and 13.9 (1H, br s).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1H-1,2,4-Triazole-3-thiol, other downstream synthetic routes, hurry up and to see.
