Abstract
ole.^ Thus, boron trichloride was passed into a melt of 2-(l-naphthyl) benzimidazole at 310- 320'in the absence of an added catalyst. Following hydrolysis, two materials were obtained. One, soluble in ethanol, dimethylformamide, acetic acid, aqueous hydrochloric acid, and aqueous alkali, proved to be the desired 2-(8-borono-1-naphthyl) benzimidazole. It was isolated in 24% yield. The other, insoluble in alcohol and in 10% aqueous sodium ...
