2-aminopyridines with alkynoic acids has been developed for the synthesis of 2-haloimidazo[1,2-a]pyridines. In this reaction, two C-N bonds and one C-halogen bond are formed in one pot, generating the desired products in good yields. This is the first report for the synthesis of 2- haloimidazo [1,2-a]pyridine derivatives from alkynoic acids.
