107534-96-3, The chemical industry reduces the impact on the environment during synthesis 107534-96-3, name is 3-((1H-1,2,4-Triazol-1-yl)methyl)-1-(4-chlorophenyl)-4,4-dimethylpentan-3-ol, I believe this compound will play a more active role in future production and life.
Example 8 Synthesis of 2-{2-[2-(4-chloro-phenyl)-ethyl]-2-hydroxy-3,3-dimethyl-butyl}- 2,4-dihydro-[1 ,2,4]triazole-3-thioneTo an ice-cold solution of 1 -(4-chloro-phenyl)-4,4-dimethyl-3-[1 ,2,4]triazol-1 -ylmethyl- pentan-3-ol (236 mg, 0.77 mmol) in 2 mL of THF was added a solution iPrMgCI in THF (2.0 M, 1 .0 mL, 2.0 mmol). The solution was warmed to 40 C and kept at that temperature for 90 min. Then, it was cooled to 0 C and treated and a suspension of sulfur (75 g, 2.34 mmol) in 1 mL of THF was added portionwise and the mixture stirred for another 60 min at 0 C. The solution was then poured onto 4% HCI (20 mL). The a- queous phase was extracted with TBME (2×30 mL). The combined org. phases were successively washed with water and brine. The crude product was obtained after drying over Na2S04 and removal of all volatiles. Purification was accomplished through flash column chromatography on silica (cyclohexane/EtOAc mixtures) to obtain the product as a colorless liquid (151 mg, 0.44 mmol, 58% yield).1H N R (DMSO-de. 500 MHz): delta (ppm) = 8.40 (s, 1 H); 7.29 (d, J = 12.0 Hz, 2 H); 7.18 (d, J = 12.0 Hz, 2 H); 4.51 -4.58 (m, 2 H); 4.00-4.06 (m, 1 H); 2.61 (dt, J = 5.0 Hz, J = 17.0 Hz, 1 H); 2.20-2.30 (m, 1 H); 1 .94-2.04 (m, 1 H); 1 .70 (dt, J = 5.0 Hz, J = 19.0 Hz, 1 H); 0.94 (s, 9 H).
The chemical industry reduces the impact on the environment during synthesis 3-((1H-1,2,4-Triazol-1-yl)methyl)-1-(4-chlorophenyl)-4,4-dimethylpentan-3-ol. I believe this compound will play a more active role in future production and life.
