Versuchsvorschrift

(E)-3-(2-Methylbut-2-enyloxy)azetidine hydrochloride (168 mg, 0.94 mmol), EDCI (182 mg, 0.94 mmol), HOBt (132 mg, 0.94 mmol) and diisopropylethylamine (276 μL, 1.58 mmol) were successively added to a solution of (E)-3-(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)-acrylic acid hydrochloride (161 mg, 0.63 mmol) in dimethylformamide (12 mL) at room temperature. The reaction mixture was stirred overnight then diluted by addition of ethyl acetate (40 mL) and water (40 mL). The aqueous layer was separated and extracted with ethyl acetate (2×40 mL). The combined organic phases were washed with a saturated solution of sodium chloride (3×50 mL), dried over sodium sulfate, filtered and concentrated to dryness. The residue was purified by chromatography on silica gel using dichloromethane/methanol (98:2) as eluent. After trituration in diethyl ether, petroleum ether and methanol, the title product was obtained as a white solid (46 mg, 21%).
