摘要: A series of substituted 3- and 4-(3-aminophenyl)pyridines has been prepared as intermediates for the synthesis some 1-alkyl-1,4-dihydro-4-oxo-7-pyridinyl-3-quinolinecarboxylic acids. The Hantzsch, Hauser other pyridine syntheses were used. 4-(3-Aminophenyl)pyridine was via 3-(4-pyridinyl)-2-cyclohexen-1-one using Semmler-Wolff reaction.
