Abstract: Abstract Imidazopyridines can exist in several tautomeric forms such as benzimidazole or purine condensed systems. Regioselectivities were determined for N-alkylations of 2-(3,4-dimethoxyphenyl)- imidazopyridines and their 4 and 5-oxides (2–4, 13, 14) with n-butyl and 4-fluorobenzyl… read more here.
