2,5-dichlorophenylthioglycolic acid derivative and method for its production

The present invention is directed to novel 2,5-dichlorophenylthioglycolic acid derivative, a process for their production and a process for producing the desired product 2,5-dichlorophenylthioglycolic acid derived from said novel compounds. 2,5-dichlorophenylthioglycolic acid derivative of the present invention can be obtained by reacting 2,4,5-trichlorobenzensulfonates and thioglycolic acid in the presence of base, and said desired product can be obtained by desulfonating said compound in an aqueous solution of mineral acid. Novel 4-carboxymethylthio-2,5-dichlorobenzenesulfonates of the present invention can be used advantageously as an intermediate for the production of 2,5-dichlorophenylthioglycolic acid. The use of said intermediate makes it possible to obtain the desired product in a decreased process steps with high yield. In addition, it poses no problem of environmental pollution as pointed out with conventional methods because it uses no heavy metals.
