실험 절차

Methyl iodide (1.3 mL) was added to a mixture of 6-chloro-4-methyl-2H-pyridazin-3-one (2.70 g) and K2CO3 (3.40 g) in dimethylformamide (27 mL). The resulting mixture was stirred at ambient temperature overnight. Then, water was added and the mixture was extracted with ethyl acetate. The combined organic extracts were washed with water and brine and dried (MgSO4). After removal of the solvent, the title compound was obtained as a solid.
