Procedure

2-Acetyl-1,3-cyclopentanedione (3.13 g.) was treated with 3,4-dichlorobenzaldehyde (4.36 g.) in 140 ml. of ethanol under reflux for 4 hours in the presence of 5 ml. of morpholine. After cooling, the reaction mixture was poured into 150 ml. of water containing 7 ml. of conc. hydrochloric acid. Deposited crystals were separated by filtration and washed with water, and dried. 2-(3,4-Dichlorocinnamoyl)-1,3-cyclopentanedione (2.48 g., 37%) was obtained which showed mp. 190°- 191° C. after recrystallization from dioxane.
