Reaction Steps

To a solution of 1.82 g of the compound obtained in Example 1 dissolved in 50 ml of ethanol was added 500 mg of 5% palladium on charcoal. Catalytic reduction was carried out under atmospheric pressure for about 1 hour. The catalyst was removed by filtration, and the solvent was removed under reduced pressure to yield the titled compound. This product was used in the next step without further purification.
