摘要
[目的]研究杀菌剂氟喹唑的合成路线。[方法]以2-氨基-5-氟苯甲酸为初始原料,经"一锅法"缩合闭环、氯化,亲核取代反应,得到目标产物氟喹唑。[结果]在优化的反应条件下,反应总收率为67.1%(以2-氨基-5-氟苯甲酸计),纯度99%;产物结构经HPLC-MS、1H NMR确证。[结论]该路线条件温和,收率高,可以作为氟喹唑的一种有效合成方法在工业上进行推广应用。
[Aims] This article aims to study the synthetic route of fluquinconazole. [Methods] Fluquinconazole was obtained from 2-amino-5-fluorobenzoic acid through reactions of condensation and ring-closure by one-pot method, chlorination and nucleophilic substitution. [Results] Under the optimal reaction conditions, the total yield of fluquinconazole was 67.1% based on 2-amino-5-fluorobenzoic acid, the purity was 99%. The structure was confirmed by HPLC-MS, 'H NMR. [Conclusions] This method can be used as an effective path to synthesize fluquinconazole in industrial scale for the advantages of mild reaction condition and high yield.
