실험 절차

To a solution of 3-(3-methylbenzofuran-2-yl)azetidine hydrochloride (19.9 mg, 0.089 mmol) in DMF (2 mL) were added (E)-3-(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)acrylic acid hydrochloride (15.8 mg, 0.062 mmol), EDCI.HCl (19.9 mg, 0.104 mmol), HOAt (14.0 mg, 0.103 mmol) and N,N-diisopropylethylamine (58 μL, 0.339 mmol). The reaction was stirred at rt for 21 h, after which the mixture was partitioned between EtOAc and H2O. The layers were separated and the aqueous layer extracted with EtOAc. The combined organic layers were washed with brine (3×), dried with Na2SO4 and concentrated. The residue was triturated twice with Et2O and the dried to yield (the title compound (14.0 mg, 58%) as a pale orange solid.
