Participants

Reaction Steps

5-(4-Aminophenyl)-1H-naphtho[1,2-b][1,4]diazepine-2,4(3H,5H)-dione obtained in Example 1, (3) (15 mg, 0.047 mmol), and 3-bromobenzenesulfonyl chloride (24 mg, 0.095 mmol) were treated by heating in pyridine (1.0 mL). After the disappearance of the starting materials was confirmed, the same treatment as that of Example 145 was performed to give the title compound (15 mg, yield 60%) as slightly brown amorphous.
