Procedure

To a solution of (5-fluoro-1-methyl-1H-indol-2-yl)-N-methylmethanamine (70 mg, 0.36 mmol) in DMF (5 mL) were added in sequential order (E)-3-(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)acrylic acid (72 mg, 0.33 mmol), 1-hydroxybenzotriazole (49 mg, 0.36 mmol), diisopropylethylamine (191 uL, 1.1 mmol), and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide (72 mg, 0.36 mmol). The mixture was stirred at room temperature overnight, cooled in an ice bath and water added with rapid stirring. The product precipitated and was filtered, triturated with ether and dried to yield title compound as a pale brown solid (97 mg, 76%): 1H NMR (300 MHz, DMSO-d6) δ 10.68 (s, 1H), 8.40 (s, 1H), 8.08-8.18 (m, 1H), 7.91-8.08 (m, 1H), 7.52-7.68 (m, 1H), 7.37-7.52 (m, 1H), 7.13-7.36 (m, 2H), 6.42 (s, 1H), 4.86-5.06 (rotamers, 2s, 2H), 3.71 (s, 3H), 3.14 (m, 2H), 2.81-2.97 (m, 2H), 2.75 (s, 3H); MS (ESI) m/e 393 (C22H21FN4O2+H)+.
