Reaction Steps

The compound obtained in Example 9 was dissolved in 66 ml of ethanol. To the resulting solution, was added 1.1 g of palladium-barium carbonate. The interior of the flask was then replaced with hydrogen. The solution was stirred at room temperature for 6 hours, and then the catalyst was filtered through Celite. The resulting filtrate was concentrated and then purified by silica gel column chromatography to provide 794 mg (94%) of the title compound.
