Popis: | By refluxing o-phenylene diamines and α-methyl-butyrolactone or γ-thiol-butyrolactone in conc. HCl 2- (γ-hydroxy-propyl) - or 2-(γ-mercapto-propyl) -benzimidazoles are obtained. By further heating or by carrying out the reaction in an excess of the lactone in some cases selfalkylation of the benzimidazoles occurs. The reaction of some more lactones with diamines is described. |
