Procedure

A mixture of 0.59 g of the 2-propenyl compound (prepared as described in Reference Example 9), 0.30 g of 5% palladium on carbon and 6 ml of ethanol was stirred at room temperature for 1.5 hours under an atmosphere of hydrogen, and the catalyst was filtered off. After evaporation under reduced pressure, the residue was purified by column chromatography on silica gel using a mixture of chloroform and ethanol (99:1) as eluent to give 0.57 g of the title compound having the following physical characteristics:
