실험 절차

15 g of piperonal (0.1 mole) and 12.6 g of 6-methyl-5-heptene-2-one (0.1 mole) in an aqueous-alcoholic solution of sodium hydroxide (200 cm3 of 10% NaOH+20 cm3 of ethanol) are stirred for 15 days at ambient temperature. The product obtained is filtered off, washed with water, and recrystallised from ethanol.
