Abstrakt: In a novel synthesis, from 2-methyl-2-halomethylbenzimidazo[2,1-b]thiazolidinium salts, by means of their recyclization under the influence of alkali, N-(2-methyl-2, 3-epithiopropyl)benzimidazol-2-ones have been obtained. Syntheses of the indicated salts from N-methallylbenzimidazole-2-thiones are described.
