Abstract:A route suitable for industrial production of secnidazole was improved,in which boron trifluoride etherate was used in replacing sulfuric acid as the catalyst. The process afforded the target product in a higher yield and with less by-products compared to traditional methods. The compound structure was confirmed with 1H NMR.
Key words:boron trifluoride etherate,secnidazole,synthesis
