948549-53-9 - Reference Information
| Use | 3-bromo-4-chlorobenzonitrile is a pharmaceutical intermediate, which can be obtained after bromination from 4-chlorobenzonitrile. 3-Bromo-4-chlorobenzonitrile can be used to prepare 2-(3-cyano-4-(4-cyanophenyl) phenyl) -4-methyl-1, 3-selenazol-5-formic acid, which is a hyperuricemia treatment and/or prevention drug and a drug for gout, arthritis or heart failure caused by hyperuricemia. |
| preparation | 5g(3.63mmol) of 4-chlorobenzonitrile is added into 100mL of 70% sulfuric acid, under stirring, 6.5g(5.98mmol) of potassium bromate is slowly added in batches, the addition is completed for 3 hours, then the reaction is carried out at room temperature for 4 hours, filtration is carried out, drying is carried out to obtain 5.5g of white solid, the content is 98% by GC, and the yield is 70%. MS:217[M H]. |
