Participants

Reaction Steps

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), pyridin-3-yloxyacetic acid hydrochloride (23 mg, 0.12 mmol), WSC.HCl (23 mg, 0.12 mmol), and dry pyridine (1 mL) were mixed, and the mixture was stirred at room temperature for 4 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 washed with ethyl acetate and hexane to give 5-[4-[2-[(pyridin-3-yl)oxy]acetylamino]phenyl]-1H-naphtho[1,2-b][1,4]diazepine-2,4(3H,5H)-dione (41 mg, yield 91%) as yellow crystals.
