실험 절차
Toluene-4-sulfonic acid 3-methoxy-4-methyl-7-oxo-7H-5,10-diaza-benzo[c]fluoren-6-yl ester (Example 18c-1) (25 mg) was suspended in N,N-dimethylethylenediamine (0.5 ml) and the mixture was stirred at 80° C. for one hour. The mixture was diluted with dichloromethane and washed with saturated ammonium chloride solution and water. The organic layer was dried over anhydrous sodium sulfate and evaporated to dryness. The residue was purified by silica gel column chromatography developed by dichloromethane-methanol=50:1 and dichloromethane-methanol=10:1. The desired product was obtained as a reddish powder (21 mg). ESI−MS: m/z 363 (MH+); 1H-NMR (CDCl3): δ2.36 (6H, s), 2.51 (3H, s), 2.66 (2H, t, J=6.5 Hz), 3.82 (2H, quartet like, J=ca 6.5 Hz), 4.02 (3H, s), 7.12 (1H, d, J=9 Hz,), 7.18 (1H, brt, J=ca 5.5 Hz), 7.54 (1H, dd, J=4.5 Hz, 1 Hz), 8.05 (1H, d, J=9 Hz), 8.80 (1H, d, J=4.5 Hz), 9.27 (1H, d, J=1 Hz).
