Versuchsvorschrift
A solution of 3-amino-6-methoxypyridazine (1.25 g, 10.0 mmol) in a mix of 1:1 THF:MeCN (20 mL), and pyridine (0.83 g, 1.5 mmol) was treated dropwise with phenylchloroformate (1.65 g, 10.5 mmol) in THF (10 mL). After stirring for 3 h, the resulting solid was collected and dried to provide the title compound (2 g, 81%).
