Procedure

41.41 g (138 millimols) of tetrachlorophthalic acid N-methylimide, 19.42 g (138 millimols) of p-methoxythiophenol, 57.43 g of potassium carbonate and 410 ml of tetrahydrofuran are stirred at 25° C. for 24 hours. After evaporation, the residue is acidified and extracted with methylene chloride. After drying and evaporation, the residue is recrystallised from toluene. This yields 35.38 g (64% of theory) of the title imide; melting point 182°-6° C.
