반응 단계

To 1.0 g of 2-n-butylsulfonylamino-5-[pyridazin-3(2H)-on-6-yl]indane dissolved in 30 ml of dimethylformamide were added 828 mg of potassium carbonate and 547 mg of benzyl bromide, and the mixture was stirred at room temperature for 2 hours. Water was added to the reaction mixture, and crude crystals precipitated were collected by filtration, dried and then recrystallized from ethanol to obtain 1.15 g of 2-n-butyl sulfonylamino-5-[2-benzylpyridazin-3(2H)-on-6-yl]indane. This compound had the same physical property values as those of the compound obtained in Example 85.
