Procedure

A mixture of Example 199A (1.2 g, 3.6 mmol), Pd/C (0.42 g), and ethyl acetate (25 mL) was hydrogenated at 4 atmospheres in a Parr shaker at room temperature for 3 days. The catalyst was removed by filtration, solvent was evaporated, and the crude product was purified by flash column chromatography on silica gel with 30% ethyl acetate/hexanes to provide the desired product. MS(DCI) m/e 348 (M+H)+.
