実験手順
3.50 g of 2-methoxyphenyl hydrazine hydrochloride was dissolved in 60 ml of ethanol, and 2.06 ml of acetyl acetone was added and heated at reflux for 1 hour. To the reaction mixture was added 150 ml of water, neutralized with saturated aqueous solution of sodium carbonate, and extracted with 150 ml of ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure and purified by silica gel column chromatography (n-hexane:ethyl acetate=2:1) to yield 3.88 g of the title compound.
