Versuchsvorschrift
15 g of piperonal (0.1 mole), and 14.3 g of 3-morpholinoacetone (0.1 mole) are mixed in an aqueous-alcoholic sodium hydroxide solution (300 cm3 of 10% NaOH and 30 cm3 of ethanol). The mixture is stirred for 4 hours and the product obtained is then filtered. The product is rinsed with water and recrystallised from ethanol.
