실험 절차

2 g (6.08 millimols) of tetrachlorophthalic acid N-2-hydroxyethylimide, 3.1 g (24.93 millimols) of p-thiocresol, 5.08 g (36.78 millimols) of potassium carbonate and 20 ml of N,N-dimethylformamide are stirred at 25° C. for 1 hour. After evaporation, the residue is acidified with dilute HCl solution and extracted with methylene chloride. After recrystallisation from toluene/cyclohexane, 3.21 g (78% of theory) of the title compound are obtained; melting point 161°-2° C.
