1-Acylmethyl-2-(omega-hydroxyalkylamino)benzimidazoles were synthesized and their behavior under various conditions was investigated: at the thermolysis without solvent, at heating in DMF or in 2-aminoethanol, hydrohalic acids, and acetic anhydride, in the presence of chlorinating agents (SOCl(2), POCl(3)). Depending on the reaction conditions derivatives were obtained of 1H-imidazo[1,2-a]-benzimidazole, 9H-2,3-dihydroimidazo[1,2-a]benzimidazole, and 10H-2,3,4,10-tetrahydropyrimido[1,2-a]-benzimidazole that were suitable synthons for the synthesis of functionally substituted derivatives of these tricyclic systems.
