摘要
以４，６－二氟嘧啶－２－异氰酸酯与邻乙氧羰基苯磺酰胺在甲苯中反应，进一步与甲醇钠作用，制备出豆田除草剂氯嘧磺隆。其结构经ＩＲ、￣１ＨＮＭＲ分析而确认。
Dichloropyrimidinylisocyanate was reacted with O-ethoxycarbonylbenzenesulfonamide in toluene and the product obtained was treated further with sodium methoxide to afford the herbicide chlorimuron-ethyl.The structure was confirmed by IR and ￣1HNMR
