実験手順

To a solution of 3-(benzofuran-2-yl)azetidine hydrochloride (30 mg, 0.086 mmol) and (E)-3-(1′-methyl-2-oxo-2,4-dihydro-1H-spiro[[1,8]naphthyridine-3,4′-piperidine]-6-yl)acrylic acid hydrochloride (20 mg, 0.059 mmol) in dry DMF (4 mL) were added EDCI.HCl (17.02 mg, 0.089 mmol), HOAt (12.09 mg, 0.089 mmol) and DIPEA (51 μL, 0.296 mmol). The reaction was stirred at room temperature overnight. The mixture was partitioned between dichloromethane and H2O, the layers were separated and the aqueous layer was extracted with dichloromethane (2×5 mL). The combined organic layers were washed with brine (3×3 mL), dried over Na2SO4 and concentrated. The residue was chromatographic purified (silica gel, eluent dichloromethane/7M NH3 in MeOH 98:2 to 95:5). The residue was further purified by preparative LCMS (Waters X-Bridge 50×19 mm 5 μm ODB in combination with Waters X-Bridge guard 10×19 mm 5 μm, at 25 ml/min flow rate; detection of product by mass and UV signal; eluent 10 mM ammonia in milliQ water to 10 mM ammonia in MeCN 5% to 95% gradient), to yield the title compound (2.6 mg, 9.6%).
