실험 절차
1,2,4-Benzenetricarboxylic anhydride (356, 0.487 g, 2.53 mmol) and 4-(2-aminoethyl)morpholine (0.33 g, 2.53 mmol) were allowed to stir 2 hours at 130° C. in acetic acid (10 mL). The reaction mixture was then cooled to room temperature and the precipitated solid was collected by filtration, washed with H2O and dried under vacuum, to afford title compound 357 as a white powder (0.63 g, 82% yield). 1H NMR (DMSO) δ (ppm): 8.26 (dd, J=7.6, 1.4 Hz, 1H), 8.15 (dd, J=1.4, 0.6 Hz, 1H), 7.92 (dd, J=7.6, 0.6 Hz, 1H), 3.73 (t, J=6.5 Hz, 2H), 3.50 (t, J=4.5 Hz, 4H), 2.59 (t, J=6.5 Hz, 2H), 2.47 (overlapped with DMSO, 4H). MS: 304.3 (calc), 305.1 (obs).
