実験手順

10H-indolo[3,2-b]quinoline-11-carboxylic acid (0.5 g, 1.9 mmol) was dissolved in 20 ml of refluxing SOCl2, After 6 hours a clear solution was obtained, and all volatiles were removed in vacuo. The crude acid chloride was suspended in 10 ml of CH2Cl2. A solution of N,N-dimethylethylendiamine (0.2 mL, 2.26 mmol) and triethylamine (2.2 ml) in 10 ml of CH2Cl2 was added at room temperature, and the mixture was stirred for 14 hours. The organic phase was washed (NaHCO3, brine) and dried (MgSO4). Removal of the solvent and purification by chromatography on alumina (CH2Cl2/MeOH, 90:10) yielded the desired compound (0.38 g, 61%) as a solid. m. p. 175-176° C. 1H-NMR [MeOD, _, ppm]: 8.16 (d, J=7.8 Hz, 1H), 7.92 (m, 2H), 7.35-7.20 (m, 3H), 7.04 (m, 2H), 3.62 (m, 2H, CH2NO), 2.55 (m, 2H, CH2N(CH3)2), 2.29 (s, 6H, N(CH3)j. MS (EI, m/z) 277 (M++1).
