Abstract

Carboxyalkylmercapto - benzene - stibonic acids are obtained by diazotizing a carboxyalkylmercapto-aniline which is characterized in that the benzene ring is further substituted, or the carboxyalkylmercapto radical is in other than the 2-position, or the alkylene group in the carboxyalkylmercapto radical contains more than one carbon atom, reacting the diazo compound with an antimonite in the presence of copper and acidifying the reaction product. The substituted benzene ring may contain alkyl, alkoxy, halogen, carboxy, or acylamino radicals. The resulting stibonic acid may be converted into a carboxylate salt, e.g. a metal salt or a salt derived from a nitrogen-containing base. The carboxyalkylmercapto aniline may contain the carboxyalkylmercapto group in the 3- or 4-position. A carboxyethylmercapto aniline may be used for the process. In the examples, the following stibonic acids are prepared: 2-carboxyethylmercapto- and 2-(a -carboxyethylmercapto)-, 2 - carboxymethyl - mercapto - 4 - acetamino -, 2 - carboxymethylmercapto - 4 - methoxy -, 2 - carboxymethylmercapto - 4 - methyl -, 2 - carboxymethylmercapto - 4 - chloro -, 3 - and 4 - carboxymethylmercapto-, and 4-carboxy-2-carboxymethylmercapto - benzene - stilbonic acids. 4 - Carboxymethylmercapto - 2,3 - dimethyl-and 4 - carboxymethyl - 2 - methyl - benzene stibonic acids are also mentioned. 2 - Carboxymethylmercapto - 4 - chloro - aniline is prepared by condensing monochloroacetic acid and 2-mercapto-4-chloro-aniline in the presence of aqueous sodium hydroxide. 2 - Carboxymethylmercapto - 4 - methoxy - aniline is prepared by condensing 2-mercapto-4-methoxy-aniline and monochloro-acetic acid in the presence of aqueous sodium hydroxide. 2 - (b - Carboxyethylmercapto) - and 2 - (a - carboxyethylmercapto)-aniline are prepared by condensing the zinc mercaptide of 2-aminobenzenethiol and b -bromopropionic acid and a -bromopropionic acid respectively in the presence of aqueous sodium hydroxide. 4 - Methyl - and 4 - carboxy - 2 - carboxymethylmercapto-aniline are prepared by a similar method.ALSO:IV(b) Internal remedies comprise aqueous solutions of water soluble salts of car boxyalkylmercapto-benzene-stibonic acids in which the benzene ring is further sub stituted, e.g. with alkoxy, alkyl, halogen, carboxy or acylamino radicals, or the car boxyalkylmercapto radical is in position other than the 2-position of the benzene ring, or the alkyl radical in the carboxy alkylmercapto radical contains more than one carbon atom. An internal remedy also comprises a dilute solution of 3-car boxymethylmercapto-benzene-stibonic acid in diethanolamine.
