Sodium Fluoride → HCID 22940130, compound

Participants

Reaction Steps

In toluene (4 mL) was dissolved 200 mg (0.797 mmol) of 6-chloro-4-methoxy-3-(2-methylphenoxy)pyridazine obtained in Example 2 (1), 305 mg (0.921 mmol) of allyl-(tributyl)tin, and then, 96.8 mg (0.0838 mmol) of tetrakis-(triphenylphosphine)palladium were successively added to the solution at room temperature, and the resulting mixture was refluxed for 3 hours and 20 minutes. The reaction mixture was allowed to stand at room temperature overnight, and then, ethyl acetate, water and sodium fluoride were added to the mixture and the resulting mixture was stirred for 2 hours. The mixture was filtered through Celite, ethyl acetate was added to the filtrate, then the organic layer was separated, and washed successively with water and brine. After drying over anhydrous sodium sulfate, the solvent was removed. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate, gradient) to obtain 62.1 mg (0.243 mmol, Yield: 30.5%) of 6-allyl-4-methoxy-3-(2-methylphenoxy)pyridazine.
