실험 절차

A mixture of 1-naphthyl boronic acid (41 mg, 0.24 mmol), 3-(5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinolin-1yl)-4-(5-bromo-1H-indol-3-yl)pyrrole-2,5-dione (88 mg, 0.2 mmol) (prepared as in Example 24), tetrakistriphenylphosphine palladium (5 mol %) in toluene (4 ml), ethanol (4 ml), saturated NaHCO3 (1 ml), and water (2 ml) was heated at 100° C. under nitrogen for 5 hours. After cooling to room temperature, the mixture was extracted with ethyl acetate (3×15 ml) and concentrated. The residue was purified by silica gel chromatography, eluting with ethyl acetate/hexanes (1:4) to afford 3-(5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinolin-1-yl)-4(5-1-naphthyl-1H-indol-3-yl)pyrrole-2,5-dione as a bright red solid (70 mg, 71%). 1H NMR (CD3OD) δ: 1.80-1.92 (m, 2H), 2.72-2.80 (t, J=6.0 Hz, 2H), 3.94-3.99 (t, J=6.0 Hz, 2H), 6.50-6.58 (m, 3H), 6.66 (s, 1H), 6.72 (m, 1H), 6.98 (dd, J=8.4 Hz, J′=2.0 Hz, 1H), 7.00-7.50 (m, 2H), 7.28 (dd, J=6.8 Hz, J′=8.4 Hz, 1H), 7.38-7.43 (m, 2H), 7.61 (s, 1H), 7.72 (d, J=8.4 Hz, 1H), 7.82 (d, J=8.4 Hz, 1H), 7.97 (s, 1H).
