実験手順

0.386 g of anhydride obtained by dehydrating 4-nitrophthalic acid (including 20% of 3-nitrophthalic acid) at a temperature of about 190° C., and 0.354 g of 2,6-diisopropylaniline were mixed, and reacted at a temperature of 180° C. for 4 hours. After the reaction was finished, the reaction mixture was dissolved in ethyl acetate, dried over anhydrous magnesium sulfate and subjected to filtration. The filtrate was concentrated and dried and solidified. Then, it was recrystallized by using a mixture of hexane and ethanol, to obtain 0.352 g (yield 50%) of the specified compound.
