Vorschrift

A mixture of 4-hydroxyimino-5-methyl-5-phenyl-3-phenylamino-thiazolidine-2-thione (0.19 g), triethylamine (0.06 g) and 3,4-dichlorophenylisocyanate in tetrahydrofuran (3 ml) was stirred for 2 days at room temperature. The solvent was evaporated under reduced pressure and the residue was purified by column chromatography (chloroform) to yield 4-(3,4-Dichlorophenylcarbamoyl)oxyimino-5-methyl-5-phenyl-3-phenylaminothiazolidine-2-thione (0.13 g) having a melting point of 95-96° C.
