実験手順

To a solution of 3-(3-methylbenzofuran-2-yl)azetidine hydrochloride (21.7 mg, 0.097 mmol) and (E)-3-(1′-methyl-2-oxo-2,4-dihydro-1H-spiro[[1,8]naphthyridine-3,4′-piperidine]-6-yl)acrylic acid hydrochloride (22.0 mg, 0.065 mmol) in DMF (3 mL) were added EDCI.HCl (18.9 mg, 0.099 mmol), HOAt (13.9 mg, 0.102 mmol) and N,N-diisopropylethylamine (57 μL, 0.333 mmol). The reaction was stirred at rt for 20 h., after which the mixture was partitioned between DCM and H2O. The layers were separated and the aqueous layer extracted with DCM (3×). The combined organic layers were washed with brine (3×), dried over Na2SO4 and concentrated and the residue was purified by flash chromatography (DCM/MeOH, 5%→20%). The product (10.6 mg, 35%) was obtained as a white powder.
