Reaction Steps

EDC (0.192 g, 1.0 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 (0.254 g, 1.0 mmole), 2,3-dihydro-8-(methylaminomethyl)-1H-3a-azacyclopenta[a]indene (0.2 g, 1.0 mmole), HOBt.H2O (0.135 g, 1.0 mmole), and Et3N (0.15 mL, 1.1 mmole) in DMF (20 mL) at RT. The reaction was stirred overnight, then was poured into H2O (50 mL) and extracted with CH2Cl2 (2×30 mL). The combined extracts were washed with brine and dried (MgSO4). Flash chromatography on silica gel (5% MeOH/CH2Cl2) gave the title compound (0.1 g, 25%) a yellow solid: MS (ES) m/e 401 (M+H)+.
