実験手順

Magnesium turnings (3.05 g, 0.125 mol) were added to a solution of 3-(5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinolin-1-yl)-4(1H-indol-3-yl)pyrrole-2,5-dione (2.56 g, 6.97 mmol) in anhydrous methanol (100 ml) and heated to reflux under an atmosphere of nitrogen for 40 minutes. After cooling to room temperature the mixture was poured into ethyl acetate (300 ml), washed with IM hydrochloric acid (300 ml) and water (500 ml). The organic layer was dried over anhydrous sodium sulfate and evaporated to dryness. The residue was then purified by silica gel chromatography using 40-50% ethyl acetate in hexanes to yield (±)-trans-3-(5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinolin-1-yl)-4(1H-indol-3-yl)pyrrolidine-2,5-dione as a pale pink solid (2.3 g). 1H NMR (DMSO-d6) 400 MHz δ: 11.54 (s, 1H), 11.03 (s, 1H), 7.32-7.4 (m, 4H), 7.17 (d, 1H, J=7.2 Hz), 7.07 (t, 1H, J=7.6 Hz), 6.96 (t, 1H, J=7.6 Hz), 6.82-6.89 (m, 2H), 4.5 (dd, 2H, J=7.2 and 20 Hz), 4.07 (t, 2H, J=5.2 Hz), 2.87 (t, 2H, J=6 Hz), 2.08 (m, 2H).
