Participants

Reaction Steps

10 g of 3-ethyl-2-ethylimino-4-(4-chloro-3-dimethylsulfamoylphenyl)-1,3-thiazolidine-4-ol-hydrobromide were reacted according to Example 2c) and the yellow precipitate of 3-ethyl-2-ethylimino-4-(4-chloro-3-dimethylsulfamoylphenyl)-1,3-thiazolidine-4-ol was rapidly filtered off. The compound so obtained was treated according to Example 3c) with ethanolic hydrochloric acid and the end product was precipitated by adding diisopropyl ether. The solvent was decanted, 200 ml of water were added to the amorphous residue and the aqueous solution was lyophilized. Colorless amorphous solid body, decomposition beginning at 134° C, γ C=N 1615 cm-1.
