Procedure

A procedure similar to that described in Example 5 was carried out with 8-bromo-5-carboxy-5,6-dihydro-1H-pyrrolo[1,2,3-de]quinoxaline-2,3-dione (300 mg, 0.96 mmol) and aniline (97 μL, 1.061 mmol) to give 274 mg of the title compound (74%): mp>300° C.; 1H NMR (270 MHz, DMSO-d6) δ12.09 (s, 1H), 10.45 (s, 1H), 7.59 (d, 2H, J=7.5 Hz), 7.34 (t, 2H, J=7.5 Hz), 7.23 (d, 1H, J=1 Hz), 7.10 (t, 1H, J=7.5 Hz), 7.07 (d, 1H, J=1 Hz), 5.31 (dd, 1H, J=10, 5 Hz), 4.32 (d, 2H, J=5.6 Hz), 3.78 (dd, 1H, J=17, 10 Hz), 3.35 (dd, 1H, J=17, 5 Hz),
