Abstract

1467507 Aminobenzene carboxylic acid amides HOECHST AG 28 May 1974 [30 May 1973] 23515/74 Heading C2C Aminobenzene carboxylic acid amides are prepared by (i) reacting a nitrobenzene carboxylic acid with thionyl chloride to form the acid chloride; (ii) treating the acid chloride in aqueous medium with ammonia or a primary amine to form the acid amide; and (iii) reducing the acid amide to form the aminobenzene carboxylic acid amide; the reactions (i), (ii), and (iii) being carried out in the absence of organic solvent. The process is preferably carried out without the isolation of intermediates.
