2 g (3.95 millimols) of 4,5-bis-(p-tolylthio)-3,6-dichlorophthalic acid N-2-hydroxyethylimide, 1,51 g (8.69 millimols) of n-decane-1-thiol, 2.29 g (16.58 millimols) of potassium carbonate and 20 ml of N,N-dimethylformamide are stirred at 25° C. for 1 hour. After concentration, the residue is taken up in methylene chloride/dilute HCl solution. The extracts are dried over sodium sulfate and evaporated. After precipitation from n-hexane, 300 mg (10% of theory) of the title compound (waxy substance) are obtained.
