Abstract:3-Amino-6-trifluoromethyl quinoline is a key pharmaceutical intermediate, and its derivatives could become drug candidates with a wide range of biological activities and potential medicinal values. 3-Amino-6-trifluoromethyl quinoline was synthesized through 5 steps reactions including the Skraup condensation, de-bromination by hydrogenation, bromine substitution, palladium-catalyzed coupling and amino deprotection using 2-bromo-4-(trifluoromethyl)aniline as starting material in a total yield of 34.8%. The structure of the final product was confirmed by 1H NMR, 13C NMR and LC-MS. This multi-step synthetic process is relatively simple and suitable for industrial production.
Key words:3-amino-6-trifluoromethyl quinoline; intermediate; synthesis
