Abstract
4-Amino-2 argentomercaptobenzene-1-carboxylic acid is obtained by reacting upon 4-amino-2-mercaptobenzene-1-carboxylic acid with a silver salt. The product, in the form of its alkali salts, is efficacious in the treatment of diseases caused by bacteria; it forms an N-methyl-o -sulphonic acid with formaldehyde and bisulphite and can be diazotized and coupled with R-salt. In an example the reaction is effected with silver acetate in aqueous acetone containing ammonia; the solution is poured into a mixture of acetone and spirit and the product filtered, dissolved in diluted ammonia and the free silver compound precipitated by acid; ammoniacal silver chloride, silver fluoride, or silver nitrate may be used in place of the acetate. 4-Amino-2-mercaptobenzene-1-carboxylic acid is obtained by diazotizing 4-nitro-2-aminobenzene-1-carboxylic acid, treating with potassium and cuprous sulphocyanides, and reducing the nitrosulphocyanobenzene carboxylic acid.
