Synthetic Route of 90110-98-8, 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. 90110-98-8, name is 3-Bromo-4-(hydroxymethyl)benzonitrile, This compound has unique chemical properties. The synthetic route is as follows.
At 0-10C, anhydrous ethanol (27 mL) was slowly added dropwise into a mixture of selenium powder (2.7 g, 34.2 mmol) and sodium borohydride (1.57 g, 41.5 mmol), then heated to room temperature and stirred for 30 min, and then added with pyridine solution (7.2 mL) containing 3-bromo-4-isopropylthiomethyl benzonitrile (63) (1.8 g, 8.49 mmol). The reaction solution was heated until reflux occurred, slowly added dropwise with 2M hydrochloric acid solution (18 mL) and then stirred under reflux for 1 h. A TLC analysis indicated that the reaction was completed. The solution was cooled to room temperature, added with a proper amount of water and then extracted with ethyl acetate (30 mL¡Á3). The organic phase was respectively washed with 2M hydrochloric acid (20 mL) and saturated saline solution (20 mL), and dried with anhydrous sodium sulfate. The solvent was removed by means of reduced pressure distillation, so as to obtain pink 3-bromo-4-hydroxymethyl selenobenzamide (64) (1.98 g), with a yield of 79.6%.
The chemical industry reduces the impact on the environment during synthesis 3-Bromo-4-(hydroxymethyl)benzonitrile. I believe this compound will play a more active role in future production and life.
