Reaction Steps

A mixture of 6.8 g (30 mmol) of 2-(3-phenylpropenylidene)-1,3-cyclohexanedione from the preceding example, 0.7 g of 10% palladium on carbon, and 150 mL of ethyl acetate was stirred at room temperature, in an atmosphere of hydrogen, until gas uptake ceased. The catalyst was filtered with suction and the filtrate was concentrated in vacuo giving 6.7 g (97%) of the title dione as an off-white solid which was used without further purification.
