Abstract

Aromatic nucleophilic nitrogen-nitrogen exchange reaction of N,N dimethyl-5,7-bis(trifluoroacetyl)-8-quinolylamine (1) with some amino acid derivatives gave the corresponding N-[5,7-bis(trifluoroacetyl)-8-quinolyl]amino acid derivatives (2) in excellent yields. Base-catalyzed cyclization of 2 afforded fluorine-containing 1H-pyrrolo[3,2-h]quinolines (3, 4) in high yields.
