Thionyl Chloride → 5-[4-[(2-Ethylbenzoyl)amino]phenyl]-1H-naphtho[1,2-b][1,4]diazepine-2,4(3H,5H)-dione

Participants

Reaction Steps

2-Ethylbenzoic acid (23 mg, 0.15 mmol) was treated with thionyl chloride in the same manner as that of Example 13, and then by using the resultant together with 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), the title compound (26 mg, yield 58%) was obtained as slightly brown crystals in the same manner as that of Example 1, (4).
