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,932-22-9
0495-1 ((Chloromethoxy)methyl)benzene (2.17 mL) was added to a mixture of 4,5-dichloropyridazin-3(2H)-one (2.00 g), 1,8-diazabicyclo[5.4.0]undeca-7-ene (1.85 mL), and N-methylpyrrolidone (24 mL) under ice-cooling, followed by stirring at room temperature for 1 hour. After water and ethyl acetate were added to the reaction mixture, the organic layer was collected by separation, washed sequentially with water and a saturated sodium chloride aqueous solution, and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure, thereby obtaining 2-((benzyloxy)methyl)-4,5-dichloropyridazin-3(2H)-one (2.82 g). MS m/z (M+H): 285.
As the paragraph descriping shows that 932-22-9 is playing an increasingly important role.
