Reaktionsschritte

200 mg of 2-methoxyphenyl hydrazine hydrochloride was dissolved in 4 ml of ethanol, and 134 μl of 3-methyl-2,4-pentanedione was added and heated at reflux for 3 hours. To the reaction mixture was added 50 ml of water, neutralized with a saturated aqueous solution of sodium carbonate, and extracted with 60 ml of ethyl acetate. After the organic layer was dried over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure to yield 209.8 mg of the title compound.
