The synthesis of hitherto unreported 5-amino-7-alkoxy2-methyl-2,4-aryl-1,2-dihydro-1,6-naphthyridine-8-carbonitriles (4) was accomplished by a one-potpseudofive-componentreaction using aryl methyl ketones or alkyl methyl ketones, malononitrile, and alcohols in the presence of sodium hydroxide under reflux conditions. By following an identical reaction procedure, various 5-amino-2-methyl-2,4
