Procedure

EDC (198 mg, 1.0 mmol) was added to a solution of (7-ethyl-3-methyl-1H-indol-2-yl)-N-methanamine (150 mg, 0.8 mmol), (E)-3-(3-oxo-3,4,dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-yl)acrylic acid hydrochloride (224 mg, 0.87 mmol) HOBT.H2O (107 mg, 0.8 mmol) and DIPEA (0.57 mL, 3.1 mmol) in dry DMF (5 mL). After heating overnight, water was added. The precipitate that formed was washed with ethyl acetate and dried (184 mg, 59%). 1H NMR (300 MHz, DMSO-d6) δ, 11.42 (s, 1H), 10.45 (s, 1H), 8.24-8.05 (rotamers, s, 1H), 7.98-7.80 (rotamers, s, 2H), 7.54 (d, J=7.4 Hz, 1H), 7.24 (m, 1H), 7.14 (m, 1H), 6.98 (s, 1H), 4.90-4.78 (rotamers, s, 2H), 3.05 (s, 2H), 2.84 (s, 3H), 2.45 (s, 3H), 2.31 (s, 3H); m/e 391.1 (C22H22N4O3+H)+.
