ChemInform Abstract

The imidazopyridine (I) is subjected to reaction with benzoyl chloride (II) under various conditions. Heating in xylenes or treatment with triethylamine/acetonitrile result in the formation of the salt (III) which is rearranged to give the 3-benzoyl derivative (IV). Friedel—Crafts acylation of (I) with (II), however, produces the 1-benzoylimidazopyridine (VI) via the intermediate salt (V). An isomerization process between (IV) and (VI) is not observed. The N-benzylimidazole (VII) is transformed into the 2-benzoylimidazole (VIII).
