실험 절차
0.871 g (5.37 mmol) of homophthalic anhydride and 0.4 g (4.30 mmol) of aniline were mixed, and melted at a temperature of 200° C. for 1 hour. The reactant was dissolved in ethyl acetate, washed with aqueous NaHCO3 solution, with water and then with saturated aqueous sodium chloride, dried over anhydrous MgSO4, and subjected to filtration with a folded filter paper. The filtrate was concentrated and evaporated to dryness. The residue was recrystallized by using a mixture of CH2Cl2 and hexane, to obtain 0.565 g (yield 68%) of the specified substance as light yellow granulated crystals. It showed the following physical properties and analyzed values.
