Versuchsvorschrift

Acetophenone (0.5 g) and sodium hydroxide (0.17 g) were suspended in 15 Ml of methanol pre-chilled at −10° C. p-Anisaldehyde (0.57 g) was added thereto, and stirred for 10 hr at room temperature. After neutralization with 5% hydrochloric acid solution, the product was extracted with 100 Ml of ethylacetate. The extracted organic phase was dried with anhydrous magnesium sulfate, and concentrated under vacuum evaporator. Purified compound was obtained by elution with n-hexane:ethylacetate (v/v, 1:7) through silica gel column chromatography (5×3 cm, Merk), and identified as follows:
