Abstract One-pot synthesis of new biologically active 4-(1 H-benzimidazol-2-yl) benzene-l, 3- diols has been developed. The compounds were prepared by the reaction of aryl-modified sulfinylbis [(2, 4-dihydroxyphenyl) methanethione] s with benzene-l, 2-diamines. Their structures were identified using elemental, IR, 1 H-NMR, and mass spectra analyses. The developed method offers short reaction times, relatively large-scale synthesis, easy and ...
