Procedure

5-(4-Aminophenyl)-1H-naphtho[1,2-b][1,4]diazepine-2,4(3H,5H)-dione (32 mg, 0.1 mmol) obtained in Example 1, (3), 2-(pyridin-2-yloxy)acetic acid (23 mg, 0.15 mmol), HATU (23 mg, 0.15 mmol), triethylamine (0.04 mL), and dry dimethylformamide (1 mL) were mixed, and the mixture was stirred at room temperature for 2 hours. This reaction mixture was added with water, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (methanol/chloroform=1/50) to give the title compound (22 mg, yield 49%) as pale yellow crystals.
