実験手順
3.5 g (20 mmol) of 2-acetyl-6-(1-propenyl)phenol and 2.1 g (20 mmol) of benzaldehyde are dissolved in 20 ml of ethanol, 4 ml of concentrated NaOH are added, the mixture is stirred overnight, the red crystal slurry is diluted with methanol and acidified with concentrated HCl and, after cooling, the product is filtered off with suction. Orange-red crystals of melting point 95°-98° C. are obtained.
