A three-component reaction of nitroarenes, aldehydes, and phenylacetylene in the presence of indium in dilute hydrochloric acid produces quinoline derivatives under reflux. The conversion involves reduction of the nitroarenes to anilines followed by coupling of the anilines, aldehydes, and phenylacetylene, followed by cyclization of the resulting species and dehydrogenation of the cyclic intermediates.
