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.

2-Carbomethoxy-3-hydroxyquinoxaline-di-N-oxide was identified as an efficient novel ligand for the copper-catalyzed coupling of aryl halides with various phenols under mild conditions. The catalytic system shows great functional-group tolerance and excellent reactive selectivity.

, p. 1509 - 1513 (2007/10/03)
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. 2005 Pleiades Publishing, Inc.
