Synthetic Route of 22034-13-5, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 22034-13-5, name is 4-Bromobenzo[c][1,2,5]thiadiazole, This compound has unique chemical properties. The synthetic route is as follows.
2000mL 1-neck flask (one neck flask) for 4-bromo-benzo [c] [1,2,5] thiadiazole (10g, 46.5 mmol), NaBH4 (17.6g, 465 mmol) were placed into a 900mL EtOH after stirring at room temperature for 16 hours. When the reaction is complete, remove the solvents by rotary evaporation the drier and extracted with CHCl3. Thus extracted organic layer was washed with brine solution. Thereafter, the dried organic layer was again put on MgSO4 and the solvent removed by evaporation dryer to give the title compound C-2-1 (8.0g, 47.6 mmol, 92percent).
The chemical industry reduces the impact on the environment during synthesis 4-Bromobenzo[c][1,2,5]thiadiazole. I believe this compound will play a more active role in future production and life.
