実験手順

1H-Benzimidazole-2-carboxylic acid monohydrate (14 mg, 0.077 mmol), 5-(4-aminophenyl)-1H-naphtho[1,2-b][1,4]diazepine-2,4(3H,5H)-dione (23 mg, 0.072 mmol) obtained in Example 1, (3), dimethylformamide (1.4 mL), and 1-hydroxybenzotriazole monohydrate (11 mg, 0.08 mmol) were mixed, and the mixture was stirred at room temperature for 3 hours. This reaction mixture was added with water, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium hydrogencarbonate, and then 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 (hexane/ethyl acetate=4/1), and then recrystallized from ethyl acetate/hexane to give the title compound (15 mg, yield 43%) as slightly yellow crystals.
