Procedure

2 g (3.71 millimols) of tetrabromophthalic acid N-phenylimide, 2.34 g (16.7 millimols) of o-methoxythiophenol, 3.34 g (24.2 millimols) of potassium carbonate and 20 ml of tetrahydrofuran are stirred at 25° C. for 24 hours. After acidification, the mixture is extracted with methylene chloride, the extracts are dried and evaporated and the residue is recrystallised from toluene. This yields 2.75 g (96% of theory) of the title imide; melting point 142°-6° C.
