3 Procedure for the preparation of 6-chloropyridazin-3(2H)-one
In a 50mL round-bottom flask were added a solution of absolute ethanol (10 mL) and dichloropyridazine (1.00 g, 6.71 mmol). The mixture was stirred at reflux of ethanol for 24 h. After cooling down to room temperature, a saturated NH4Cl solution (30 mL) was added and the resulting solution was extracted with CH2Cl2 (330 mL). The combined organic layers were dried over Na2SO4, filtered, and evaporated under vacuum. The crude solid was triturated in petroleum ether, filtered through a Buchner to afford the pure product (0.785 g, 90%).
