Abstract
N-Methylcarbazole-3-carboxylic acid was synthesized from N-methyl-2-amino-4-carboxydiphenyl-amine through the corresponding diazo compound by a modified Pschorr procedure. The acid was converted into N-methylcarbazole-3-carbonyl chloride which was treated with amines containing benzo- and aza-crown ether moieties, as well as with 3-(dimethylamino)propylamine, to obtain the respective N-substituted amides.
