実験手順

2-Acetyl-1,3-cyclopentanedione (3.83 g.) was treated with 5.0 g. of 3-hydroxy-4-methoxybenzaldehyde in 120 ml. of ethanol in the presence of 5 ml. of morpholine under reflux for 5 hours. After cooling, the reaction mixture was poured into 200 ml. of water containing 8 ml. of conc. hydrochloric acid. Deposited crystals were separated by filtration, washed with water and ethanol successively, and dried. 2-(3-Hydroxy-4-methoxycinnamoyl)-1,3-cyclopentanedione (5.46 g.) was obtained, in the form of yellow crystals which showed mp. 137°-139° C. after recrystallisation from a mixed solvent of ethanol and dioxane.
