Alternative strategies for functionalizing 2-chloro-3-nitroimidazo[1,2-a] pyridine have been developed. Suzuki-Miyaura cross-coupling reaction provided easily the corresponding 2-arylated compounds, and herefrom the nitro group was reduced into amine which afforded amides, anilines, and ureas in the 3-position. The amination of the key compound using a metal-catalyzed reaction was reported. This study highlighted the importance of the nitro group to facilitate the chlorine displacement. Other nucleophilic aromatic substitutions open a route to various products derived from imidazo[1,2-a]pyridine.

The scope of the Groebke-Blackburn reaction of 2-aminoazines is limited by the availability of isocyanides. To prepare the Groebke-Blackburn type 2-phenyl-3-(hetero)arylaminoimidazo[1,2-a]azines, for which the respective (hetero)arylisocyanides are scarce
