Abstract
A suitable procedure for the reduction or transposition of derivatives of 1-hydroxybenzimidazoles -o -imidazo- (4,5-boc) -pyridines, characterized in that it consists of treating with a nucleophilic reagent a derivative of 1-hydroxybenzimidazole-p-imidazo - (4,5b oc) -pyridine, whose derivative is an ester, an ether or a derivative formed by reaction of the corresponding 1-hydroxy compound with a halide, oxyhalide, thiohalide, oxide or sulfide of an element of Group Va of the Periodic System with an atomic weight of 30 to 122, inclusive, or a halide, oxyhalide, or sulfur oxide.
