Synthesis of 1,4-Diaryl-1H,3H-pyridine-2,6-dione-3-arylhydrazones: New pyridone Azo Disperse Dyes

3-(4-Methoxy-3-methylphenyl)glutaconic anhydride (III) on treatment with arylamines and methylamine gives N-aryl-and N-methyl-β-(4-methoxy-3-methylphenyl)glutaconimides (IV-VII) which undergo coupling reactions with aryldiazonium salts in acetone to give
