Abstract: Reactions of benzimidazole as well as purine derivatives containing 1,3-pentanedione or ethyl 3-oxobutyrate moiety in their molecules with acetic anhydride were studied. N-Acetylation products and products of cyclization - imidazolothiazoles - were isolated and characterized by spectral methods. Under the reaction conditions used, no O-acetylation was observed.
