実験手順
To a stirred solution of 5-acetyl-2-ethyl-4-nitro-6-phenylpyridazin-3(2H)-one (100 mg, 0.34 mmol) (Dal Piaz, V et al., J. Med. Chem. 1997, 40, 1417) in ethanol (2 mL), 3-chloroaniline (132 mg, 1.04 mmol) was added portionwise. The resulting mixture was stirred at room temperature for 30 min and the final product was collected by filtration and washed with ethanol and diethylether to yield the title compound (65% yield).
