摘要
由邻甲氧羰基苯磺酰胺和氯甲酸甲酯为起始原料,经过酯化、胺解二步反应合成了苯磺隆,确定了各步反应的较佳工艺条件。总收率为81.3%,原药纯度达96%。该工艺具有原料易得,反应步骤少等特点。
Tribenuron-methyl was synthesized in a two-step process involving esterification and amide using 2-methoxycarbonylstdfamoylbenzoate and methyl chloroformate as starting material. Synthesis condition were optimized for each step. Overall yield reaches 81.3% the product purity was 96%. This process features the advantages of ready availability of reactants and few reaction steps.
