8.8 g of 4-(4-chloro-3-chlorosulfonylphenyl)-3-methyl-2-methylimino-1,3-thiazolidine-4-ol-hydrobromide were introduced portionwise at 20° C. in a stirred mixture of 4 g of cyclopentylmethyl amine, 8 g of triethyl amine and 100 ml of ethanol and the reaction mixture was allowed to stand over night. The solvent was distilled off under reduced pressure and the amorphous end product was crystallized under 80 ml of water. Colorless solid body, decomposition beginning at 80° C., γ C=N 1620 cm-1.
