実験手順

EDC (0.35 g, 1.81 mmole) was added to a solution of (E)-3-(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)acrylic acid hydrochloride salt (0.42 g, 1.65 mmole), 1-ethyl-3-(methylaminomethyl)-1H-indole (0.31 g, 1.65 mmole), HOBt.H2O (0.24 g., 1.81 mmole) and diisopropylethylamine (0.86 mL, 4.95 mmole) in DMF (15 mL) at RT. The reaction was stirred overnight then was concentrated in vacuo. The residue was diluted with water and extracted with ethyl acetate. The combined organic extracts were washed with brine and dried over Na2SO4. Flash chromatography on silica gel (10% EtOH/EtOAc) gave title compound (0.39 g, 61%) as a light yellow solid after drying in vacuo: MS (ES) m/e 389 (M+H)+.
