The present invention relates to a process for preparing 1-aryl-4-oxopyrrolo[3,2-c]quinoline derivatives through reaction of 4-oxofuro[3,2-c]quinoline compounds with aniline compounds under mild conditions in a single step, wherein 1-aryl-4-oxopyrrolo[3,2-c]quinoline derivatives having various substituents may be prepared in high yield, so that the 1-aryl-4-oxopyrrolo[3,2-c]quinoline derivatives may be utilized as an intermediate for producing a reversible inhibitor of gastric acid secretion. |
