Various 5,7-bis(trifluoroacetyl)-8-quinolylamines were synthesized in excellent yields by aromatic nucleophilic N-N exchange reaction of N,N-dimethyl-5,7-bis(trifluoroacetyl)-8-quinolylamine with amines. Aromatic nucleophilic substitution with ethyl glycinate and subsequent base-catalyzed cyclodehydration afforded fluorine-containing 1H-pyrrolo[3,2-h]quinolines quantitatively.
