Procedure

To a solution of (1H-indol-5-ylmethyl)methylamine (143 mg, 0.9 mmol), (E)-3-(4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-pyrido[2,3-e][1,4]diazepin-7-yl)acrylic acid dihydrochloride (250 mg, 0.8 mmol), HOBt (121 mg, 0.9 mmol) and diisopropylethylamine (0.61 mL, 3.6 mmol) in DMF (25 mL) was added EDC hydrochloride (172 mg, 0.9 mmol). The mixture was stirred overnight at room temperature. Water (100 mL) was added and the solution was stirred for 1 hr. The precipitate was collected by filtration. The yellow solid was preabsorded onto silica gel and purified by column chromatography (95:5 CH2Cl2/MeOH) to afford (E)-N-(1H-indol-5-ylmethyl)-N-methyl-3-(4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-pyrido[2,3-e][1,4]diazepin-7-yl)acrylamide (195 mg, 63%) as a white solid and as a mixture of amide rotomers. 1H NMR (300 MHz, DMSO-d6) δ 11.07 (d, J=7.6 Hz, 1H), 10.37 (m, 1H), 8.52 (dd, J=7.0, 1.9 Hz, 1H), 8.15 (d, J=2.0 Hz, 1H), 7.59-7.26 (m, 5H), 7.07-6.92 (m, 11H), 6.38 (d, J=1.9 Hz, 1H), 4.66-4.85 (2×s, 2H), 3.74-3.77 (m, 2H), 3.42-3.38 (m, 2H), 3.08-2.90 (2×s, 3H), 2.37-2.32 (2×s, 3H); ESI MS m/z 390 [C22H23N5O2+H]+.
