932-22-9, 4,5-Dichloro-3(2H)-pyridazinone is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: To a solutionof 4,5-dichloropyridazin-3(2H)-one (1, 3.0 mmol) andEt3N (3.6 mmol) in CH2Cl2 (30 mL) was added dropwise theappropriate alkyl/aryl chloroformate (2, 3.9 mmol) and themixture was stirred for 10 min at 5 C (Scheme 1). Thereaction mixture was washed using water (5 ¡Á 50 mL). Theorganic layer was dried over anhydrous magnesium sulfate,and then evaporated under reduced pressure. The resultingresidue was recrystallized from THF/n-hexane (1:3, v/v) togive the product 3., 932-22-9
The synthetic route of 932-22-9 has been constantly updated, and we look forward to future research findings.
