Synthesis
5-Bromo-2-fluorobenzonitrile is the key intermediate of the synthetic antigout drug Febuxostat. The synthesis method comprises the following steps: reacting o-fluorobenzoyl chloride with ammonia water to obtain o-fluorobenzamide; then generating o-fluorobenzonitrile under the action of a dehydration reagent; and finally, in 75-90% sulfuric acid, brominating with dibromohydantoin to obtain 5-bromo-2-fluorobenzonitrile. The synthesis method is simple and easy to implement, mild in conditions, low in production cost, and causes no wastewater discharge.5-Bromo-2-fluorobenzonitrile ?? ?? ? ???
