Versuchsvorschrift
3-Cyano-6-methyl pyridazine (U.S. Pat. No. 5,914,319) (0.77 g, 6.4 mmol) was dissolved in methanol (20 mL), then hydroxylamine hydrochloride (0.66 g, 9.6 mmol) and triethylamine (1.3 mL, 9.6 mmol) were added and the mixture was stirred at room temperature overnight. The mixture was chilled in an ice-bath, then the solid was collected by filtration, washed with methanol and dried to give the title compound as a pale yellow solid (0.84 g).
