Procedimiento

To 320 mg of the compound prepared in (9) above were added 9 ml of dioxane and 15 ml of ethanol. The mixture was catalytically hydrogenated with 290 mg of 10% palladium-on-carbon. The catalyst was removed by filtration, the filtrate was concentrated, and the residue was subjected to silica gel column chromatography using hexane-ethyl acetate (2:1) as an eluant to obtain fractions containing the target compound. The fractions were concentrated to produce 206 mg of the title compound.
