실험 절차

3-amino-6-mercaptopyridazine (0.5 g), 4-chloromethyl-3-propylimidazole hydrochloride (0.62 g) and potassium carbonate (2.0 g) were added to N,N-dimethylformamide (10 ml), and the mixture was stirred overnight at room temperature. The solvent was distilled off, the residue was purified by basic silica gel column chromatography (elution solvent: methanol/ethyl acetate), to give 3-amino-6-[(3-propylimidazol-4-yl)methylthio]pyridazine (0.52 g) as yellow crystals.
