Reaction Steps

110 ml of 1.0 M sodium methylate solution in 110 mmols of absolute methanol are evaporated to dryness and the residue is suspended in 200 ml of dimethyl sulfoxide. 39.04 g (100 mmols) of 5-nitro-3-phenylthiophthalic acid N-p-toluylimide in 200 ml of dimethyl sulfoxide are added, the mixture is stirred for one day at 25° C. and then discharged into 1.5 liters of dilute hydrochloric acid and the resulting mixture is extracted with chloroform. The organic phase is washed three times with water, dried over sodium sulfate and evaporated. After recrystallisation from toluene/cyclohexane, 31.68 g (84% of theory) of the title imide, with a melting point of 166°-168° C., are obtained.
