A one-pot synthesis of 9-chloro-6-methyl-7-phenyldibenzo[b,h][1,6]naphthyridines from 4-chloro-2-methylquinolines is reported. Since the yield of the dibenzonaphthyridine was low, in an alternative method the title compounds were prepared from the 4-chloro-2-methylquinolines via 2-methyl-4-[(4-chlorophenyl)amino]quinolines as intermediates, which provided improved yields.
报道了从 4-氯-2-甲基喹啉中一锅法合成 9-氯-6-甲基-7-苯基二苯并[b,h][1,6]naphthyridines。由于二苯并萘啶的产率低,在替代方法中,标题化合物是由 4-氯-2-甲基喹啉通过 2-甲基-4-[(4-氯苯基)氨基]喹啉作为中间体制备的,这提供了更高的产率.
