65202-50-8, Methyl 6-chloropyridazine-3-carboxylate is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Methyl 6-chloropyridazine-3-carboxylate (1.4 g), spiro[1-benzofuran-3,3′-pyrrolidine] (1.5 g), potassium carbonate (1.4 g) and tetrabutylammonium iodide (370 mg) were suspended in tetrahydrofuran (80 mL), and the suspension was stirred under reflux overnight. The reaction mixture was diluted with ethyl acetate, and washed with aqueous sodium carbonate solution. The organic layer was dried over sodium sulfate and the solvent was evaporated under reduced pressure. Ethyl acetate-hexane was added and the resulting precipitate was collected by filtration to give the object product (2.2 g, 88%). 1H NMR (300 MHz, DMSO-d6) delta ppm 2.21-2.41 (m, 2H) 3.52-4.04 (m, 7H) 4.43-4.54 (m, 2H) 6.80-7.02 (m, 3H) 7.13-7.25 (m, 1H) 7.32 (d, J=7.35 Hz, 1H) 7.87 (d, J=9.42 Hz, 1 H)
As the paragraph descriping shows that 65202-50-8 is playing an increasingly important role.
