Procedure
Obtained by a procedure analogous to that indicated in Example 1 (b), from 2-(4-chloro-3-methylphenyl-imino)-4-(4-chloro-3-dimethylsulfamoylphenyl)-3-methylthiazolidin-4-ol hydrobromide in boiling glacial acetic acid, with subsequent precipitation with diethyl ether. Colorless crystals from glacial acetic acid; melting point 231° C. (with decomposition).
