A procedure was developed for preparing di[methoxy(ethoxy)carbonylamino-1H-benzimidazol-5-yl] ethers by the reaction of methyl or ethyl chloroformate with sodium cyanamide, followed by the reaction of the resulting methyl or ethyl cyanocarbamate with 4-(3,4-diaminophenoxy)-1,2-phenylenediamine in acidic solution.
开发了一种制备di[methoxy(ethoxy)carbonylamino-1H-benzimidazol-5-yl]醚的方法,该方法通过甲基或乙基氯甲酸酯与氰胺钠反应,然后将所得的甲基或乙基氰基氨基甲酸酯与4-(3,4-二氨基苯氧基)-1,2-苯二胺在酸性溶液中反应。
