2-Chloro-5,6,7,8-tetrahydro-N-arylquinoline-3-carboxamides were synthesized, and it was shown that the halogen can be substituted successfully by an arylamino group. 2-Arylamino-5,6,7,8-tetrahydro-N-arylquinoline-3-carboxamides are converted by reaction with ethyl chlorocarbonate into 1,3-diaryl-2,4-dioxo-1,2,3,4,6,7,8,9-octahydropyrimidoquinolines.When heated with acetic anhydride and perchloric acid they give 1,3-diaryl-2-methyl-4H-4-oxo-6,7,8,9-tetrahydropyrimidoquinolinium perchlorates.
