Versuchsvorschrift

To a suspension of 2.14 g of 4,4'-dimethylchalcone in 40 ml of acetic acid was added 0.2 g of 5% palladium on carbon. The reaction vessel was purged with hydrogen gas, and the mixture was vigorously stirred at room temperature for 8.5 hours. The reaction mixture was filtered through Celite, and the filtrate was concentrated to give 2.02 g of the title compound.
