A series of substituted 3- and 4-(3-aminophenyl)pyridines has been prepared as intermediates for the synthesis of some 1-alkyl-1,4-dihydro-4-oxo-7-pyridinyl-3-quinolinecarboxylic acids. The Hantzsch, Hauser and other pyridine syntheses were used. 4-(3-Aminophenyl)pyridine was prepared via 3-(4-pyridinyl)-2-cyclohexen-1-one using the Semmler-Wolff reaction.
已经制备了一系列取代的3-和4-(3-氨基苯基)吡啶,作为合成一些1-烷基-1,4-二氢-4-氧代-7-吡啶基-3-喹啉羧酸的中间体。使用了Hantzsch,Hauser和其他吡啶合成方法。使用Semmler-Wolff反应通过3-(4-吡啶基)-2-环己烯-1-酮制备4-(3-氨基苯基)吡啶。
