Reaction Steps

The diastereomeric mixture of intermediates from Step B (39 mg) was dissolved in absolute ethanol (1.5 mL) under argon, treated with 10% palladium on carbon (4 mg), then stirred under a hydrogen atmosphere for 8 hr. After purging the system with argon, the catalyst was removed by filtration through a pad of Celite. The solvent was removed and the product dried in vacuo to afford 32 mg of the title compound as a colorless solid. Preparative thin layer chromatography (“prep TLC”) using a 20% ethyl acetate-hexane mixture as the eluent provided the two diastereomers.
