| titleOfInvention | Preparation of 2-(2,6-dichlorophenyl)amino-phenylacetic acid or its salt |
| abstract | PURPOSE: To obtain the titled compound in high yield advantageously, by reacting a dichloroaniline derivative with a methylthioacetic acid or its derivative, followed by reaction with a halogenating agent and a Lewis acid, alkali hydrolysis and reductive desulfurization reaction. n CONSTITUTION: N-Phenyl-2,6-dichloroaniline is reacted with methylthioacetic acid or its reactive derivative at its carboxyl group, to give N-phenyl-N-methylthioacetyl-2,6-dichloroaniline. This compound is reacted with a halogenating agent (e.g., α-chlorosuccinimide, Cl, etc.) and a Lewis acid to give 1-(2,6-dichlorophenyl)-2- oxo-3-methyl-thioindoline. This compound is subjected to alkali hydrolysis and reductive desulfurization reaction successively or in the reverse order to give the desired compound. n EFFECT: The reaction process is short, the reaction conditions are mild, and environmental pollution problems will not take place. n COPYRIGHT: (C)1982,JPO&Japio |
