Versuchsvorschrift

A stirring solution of (3-chloro-2-isopropoxybenzyl)methylamine (0.229 g, 1.07 mmol) and diisopropylethylamine (0.51 mL, 2.9 mmol) in DMF (20 mL) under N2 was treated sequentially with (E)-3-(7-oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-3-yl)acrylic acid hydrochloride (0.250 g, 0.980 mmol), 1-hydroxybenzotriazole hydrate (0.144 g, 1.07 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.205 g, 1.07 mmol). After stirring for 18 h, the reaction mixture was diluted with H2O (30 mL). The resulting solids were collected by filtration and washed with Et2O (100 mL), suspended in MeOH (30 mL) and sonicated for 30 minutes. The solids were then collected by filtration, washed with MeOH and dried to yield the title compound (0.085 g, 21%) as a white solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.67-10.64 (m, 1H), 8.37-8.32 (m, 1H), 8.09-7.91 (m, 1H), 7.53-7.48 (m, 1H), 7.42-7.37 (m, 1H), 7.28-7.02 (m, 3H), 4.83-4.68 (m, 2H), 4.53-4.45 (m, 1H), 2.94-2.85 (m, 5H), 2.56-2.49 (m, 2H), 1.33-1.28 (m, 6H); MS (ESI) m/e 414 (M+H)+.
