Reactions with N-chlorosuccinimide of various 5-methylimidazo[1,2-a]pyridine derivatives with an electron-withdrawing group substituted at the 3-position
Chlorination reactions using N-chlorosuccinimide (NCS) was investigated for various 5-methylimidazo[1,2-a]pyridine derivatives with an electron-withdrawing group substituted at the 3-position. These reactions showed different results, and by examining these, we proposed a reaction mechanism via the appropriate 3-halogenoimidazo[1,2-a]pyridium compounds as the reaction intermediates.
