Abstract
4-(4-Halo-3-nitrophenyl)pyridines, useful as intermediates in the synthesis of antibacterial 1-alkyl-1,4-dihydro-4-oxo-7-pyridinyl-3-quinolinecarboxylic acids, are obtained by nitrating 4-(4-halophenyl)pyridines. The 4-(4-halo-3-nitrohenyl)pyridines may be converted to the antibacterial agents by reducing them to 4-(3-aminophenyl)pyridines and then subjecting the amino compounds to suitable known reactions.
