Versuchsvorschrift

To a solution of 0.370 g (2.25 mmol) of the product of Step H dissolved in 25 mL of absolute ethanol was added 53 mg of a 5% rhodium on carbon catalyst and the mixture was shaken under a 40 psig pressure of hydrogen on a Parr apparatus. After 30 minutes, the reaction mixture was removed, filtered and evaporated in vacuo. The residue was purified on a silica gel flash chromatography column eluted with 35% ethyl acetate/hexane to afford the title compound.
