実験手順

6-Chloro-3-hydroxy-5,9-diaza-benzo[c]fluoren-7-one (Example 34a) (27 mg) was dissolved in DMF (2 ml). To the solution were added benzyl chloride (0.016 ml) and potassium carbonate (29 mg). The mixture was stirred at 90° C. for 2 hours. The reaction mixture was dissolved in dichloromethane and the mixture was washed with 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 and dichloromethane-MeOH=50:1. The desired product (12 mg) was obtained as a light yellow solid. EI−MS: m/z 372 (M+); 1H-NMR (CDCl3): δ5.25 (2H, s), 7.30-7.55 (7H, m), 8.00 (1H, dd, J=5 Hz, 1 Hz), 8.36 (1H, d, J=9Hz), 8.95 (1H, d, 5 Hz), 9.03 (1H, d, J=1 Hz).
