High-temperature catalytic synthesis of quinolino[1,2-a]benzimid azole and some of its transformations

Article abstract of DOI:10.1007/BF01165912

The possibility of synthesis of quinoline[1,2-a]benzimidazole from aniline and quinoline on a dehydrogenating mark K-16 catalyst at 560-580°C was demonstrated. It was established that in the nitration of quinolino[1,2-a]benzimidazole, a 10-nitro-derivative is formed, whereas in the reaction with ADCE, tetramethoxycarbonylquinolino[1,2-a]pyrido[2′,1′-b]benzimidazole is formed. 1996 Plenum Publishing Corporation.
