A selected series of 2-(4-methylpyridin-2-yl)-1H-benzimidazole derivatives, bases and cyclic mono- and bis-salts, were synthesized. Complete H-1 nmr characterization is reported. Ambiguous assignments were solved using H-1-H-1 NOESY analysis. Significant ir and H-1 nmr data are presented concerning: i) tautomeric equilibrium of imidazole hydrogen; ii) hydrogen bonds; iii) conformational inversion of partially saturated rings.

Abstract

A selected series of 2-(4-methylpyridin-2-yl)-1H-benzimidazole derivatives, bases and cyclic mono- and bis-salts, were synthesized. Complete H-1 nmr characterization is reported. Ambiguous assignments were solved using H-1-H-1 NOESY analysis. Significant ir and H-1 nmr data are presented concerning: i) tautomeric equilibrium of imidazole hydrogen; ii) hydrogen bonds; iii) conformational inversion of partially saturated rings.
