Synthesis of Methyl 5(6)-(4-Aminophenoxy)- and 5(6)-(2-Aminophenoxy)-2-benzimidazolyl Carbamates and Their Biological Properties
Tóm tắt
A procedure was developed for preparation of methyl 5(6)-(4-aminophenoxy)- and 5(6)-(2-aminophenoxy)-2-benzimidazolyl carbamates by reaction of 3,4,4`-triaminodiphenyl or 3,4,2`-triaminodiphenyl ethers respectively with methyl cyanocarbamate in water solution in the presence of 7-10 molar excess of acetic acid. The helminthicidal properties, embryotoxicity, and overall toxicity of compounds obtained were estimated.
