Versuchsvorschrift

To a solution of (3-isopropylbenzofuran-2-yl)-N-methylmethanamine (115 mg, 0.57 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 (111 mg, 0.51 mmol), 1-hydroxybenzotriazole (77 mg, 0.57 mmol), diisopropylethylamine (289 uL, 1.54 mmol), and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide (109 mg, 0.57 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 the title compound as a white solid (38 mg, 17%): 1H NMR (400 MHz, DMSO-d6) δ 10.62 (s, 1H), 8.38 (s, 1H), 8.07 (s, 1H), 7.75-7.73 (d, J=7.6 Hz, 1H), 7.53-7.49 (m, 2H), 7.26-7.18 (m, 3H), 4.99-4.80 (rotamers, 2s, 2H), 3.40-3.35 (m, 1H), 3.32 (s, 3H), 2.91-2.89 (m, 2H), 2.55-2.53 (m, 2H), 1.37-1.36 (d, J=6.8 Hz, 6H); MS (ESI) m/e 404 (C24H25N3O3+H)+.
