Versuchsvorschrift

EDC (250 mg, 1.3 mmol) was added to a solution of 3-(7-Oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-3-yl)-acrylic acid hydrochloride (267 mg, 1.05 mmol), 2-methylaminomethyl-1H-indole-3-carbonitrile (186 mg, 1.0 mmol), HOBt H2O (135 mg, 1.0 mmol) and DIPEA (510 μL, 3.0 mmol) in dry DMF (4 mL). After 3 days of stirring, the mixture was diluted with water (50 mL) at 10° C. The precipitate was filtered, washed with water and dried. The solid was stirred in MeOH (10 mL), filtered and dried to afford 239 mg (62%) title compound. 1H NMR (300 MHz, DMSO-d6, δ): 12.28 and 12.09 (rotamers, 2s, 1H), 10.66 (s, 1H), 8.37 (s, 1H), 8.11 and 8.05 (rotamers, 2s, 1H), 7.52 (m, 3H), 7.22 (m, 3H), 5.13 and 4.90 (rotamers, 2s, 2H), 3.27 and 2.97 (rotamers, 2s, 3H), 2.92 (m, 2H), 2.55 (m, 2H). MS (ESI): nm/e 386 (M+H)+.
