Procedure

EDC (116 mg, 0.6 mmol) was added to a solution of (3-ethyl-1H-indol-2-yl)-N-methylmethanamine (87 mg, 0.46 mmol), (E)-3-(3-oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-yl)acrylic acid hydrochloride (123.65 mg, 1.05 mmol), HOBT.H2O (62 mg, 0.46 mmol) and DIPEA (0.33 mL, 1.8 mmol) in dry DMF (5 mL). After stirring overnight, water was added. The precipitate that formed was washed with ethyl acetate and dried to afford the title compound (76.2 mg, 42%). 1H NMR (400 MHz, DMSO-d6) δ 11.41 (s, 1H), 8.18 (s, 1H), 7.88 (s, 1H), 7.46 (t, J=7.9 Hz, 2H), 7.25 (d, J=7.9 Hz, 1H), 7.03 (t, J=7.6 Hz, 1H), 6.95 (t, J=7.1 Hz, 2H), 4.92 (s, 2H), 4.90-4.74 (rotamers, s, 2H), 4.68 (s, 3H), 3.08 (m, 2H), 1.13 (t, J=7.4 Hz, 3H); MS (ESI): m/e 391.1 (C22H22N4O3+H)+.
