Process for the preparation of 1-nitroben zene-2-carboxylic acid alkyl ester-5-carboxylic acid amides

摘要

A process for the preparation of 1-nitrobenzene-2-carboxylic acid alkyl ester-5-carboxylic acid amides, wherein 1-nitro-benzene-2,5-dicarboxylic acid dialkyl esters are reacted with ammonia in a polar organic solvent miscible with water in which the final product is obtained in a very good yield and in a very easily conducted process wherein only one reaction step must be carried out.
