PCT No. PCT/KR97/00074 Sec. 371 Date Jan. 16, 1998 Sec. 102(e) Date Jan. 16, 1998 PCT Filed May 2, 1997 PCT Pub. No. WO97/44342 PCT Pub. Date Nov. 27, 1997The 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. |
