Abstract

Edaravone belongs to a class of brain-protective agents, which can scavenge free radicals. To reduce impurities and improve the yield, a continuous flow production process of edaravone was developed. The synthesis is continuously carried out in two steps. The throughput can reach 11.328 kg/day and the purity of the final product is 99.95%, which are in accordance with the needs of production. This is an efficient and quick production process suitable for industrial production.
