Abstract: The first continuous flow synthesis of imidazo [1,2-a]pyridine-2-carboxylic acids directly from 2-aminopyridines and bromopyruvic acid has been developed, representing a significant advance over the corresponding in-flask method. The process was applied to the multistep synthesis of imidazo [1,2-a]pyridine-2-carboxamides, including a Mur ligase inhibitor, using a two microreactor, multistep continuous flow process without isolation of intermediates.
This paper was performed on the Africa system, replaced by the Asia system in 2012.
