Abstract
The reaction of chloroacetic anhydride and chloroacetic acid with N-substituted 2-aminopyridine derivatives 3 produced 1-substituted derivatives of anhydro(3-chloroacetyl-2-hydroxyimidazo[1,2-a]-pyridinium hydroxide) (4). The isomeric anhydro(1-benzyl-2-chloroacetyl-3-hydroxyimidazo[1,2-a]-pyridinium hydroxide) (10a) was prepared by a reported procedure and the spectral data of the two isomeric series of compounds were compared. The significant differences in the n.m.r. spectra of the two series were attributable to the deshielding influence of the exocyclic acyl moiety.
