Participants

Reaction Steps

3.9 g (10 mmols) of 5-nitro-3-phenylthiophthalic acid N-p-toluylimide, 1.4 g (10 mmols) of sodium thiophenolate and 80 ml of dimethyl sulfoxide are stirred for one hour at 25° C. The reaction mixture is taken up in water and chloroform and the organic phase is washed with water, dried over magnesium sulfate and evaporated. After recrystallisation from toluene, 4.1 g (91% of theory) of the title imide, with a melting point of 179°-180° C., are obtained.
