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
4,5-dichloro-2-methyl-pyridazin-3-one To a stirred solution of 4,5-dichloro-1H-pyridazin-6-one (25.0 g, 152 mmol) in N,N-dimethylformamide (152 ml) was added potassium carbonate (25.4 g, 182 mmol) and iodomethane (25.8 g, 182 mmol, 11.3 ml). The resulting mixture was stirred at room temperature overnight. The reaction mixture was then poured onto ice-water (300 ml) and the mixture stirred for 15 mins. The resulting precipitate was collected by filtration, then dissolved in dichloromethane and passed through a phase separation cartridge. The organics were concentrated in vacuo to give 19.7 g of a pale brown solid. 1H NMR (400 MHz, Chloroform) d ppm 3.83 (s, 3H) 7.77 (s, 1H)
The synthetic route of 932-22-9 has been constantly updated, and we look forward to future research findings.
