A procedure similar to that described in Example 52 was carried out with 9-bromo-5-(1-carboxyethyl)-6,7-dihydro-1H, 5H-pyrido[1,2,3-de]quinoxaline-2,3-dione (more polar) (100 mg, 0.28 mmol) and aniline (28 μL, 0.31 mmol) to give 50 mg of the title compound (41%): mp>300° C.; 1H NMR (270 MHz, DMSO-d6) δ11.92 (s, 1H), 9.46 (s, 1H), 7.32 (d, 2H, J=8 Hz), 7.23 (t, 1H, J=8 Hz), 7.21 (s, 1H), 7.19 (s, 1H), 6.99 (t, 1H, J=8 Hz), 5.13 (bd, 1H, J=9 Hz), 2.73~2.99 (m, 2H), 2.59 (qd, 1H, J=9, 7 Hz), 2.28 (dm, 1H, J=13.5 Hz), 1.72~1.92 (m, 1H), 1.13 (d, 3H, J=7 Hz).
