実験手順
Reflux 6-(3,4-dimethoxyphenyl)hex-1-en-3-one, containing a small amount of 6-(3,4-dimethoxyphenyl)-1-diethylaminohexan-3-one (6 g, produced by slow distillation of the latter substance) with 2-ethyl-cyclopentane-1,3-dione (3.5 g) in 0.12% anhydrous methanolic potassium hydroxide (10 cc) for 10 hours. Remove most of the methanol under reduced pressure, add benzene (25 cc) and ether (25 cc) and wash the solution with water, dilute aqueous potassium hydroxide, dilute hydrochloric acid and water. Dry and evaporate the solvent to give the triketone adduct 2-[6-(3,4-dimethoxyphenyl)-3-oxohexyl]-2-ethylcyclopentane-1,3-dione; infrared absorption (gum) 5.80, 6.25 μ (split peak).
