Reaction Steps

To a solution of Intermediate 1 (350 mg, 0.78 mmol) in 20 mL of MeOH was added 10% Pd/C (40 mg). A balloon filled with hydrogen gas was attached, and the reaction was stirred at 25° C. for 12 hrs. The mixture was filtered through Celite pad and the solvent was evaporated. The residue was purified by medium pressure liquid chromatography on silica gel using ethyl acetate:hexane (8:2) to yield Intermediate 13 as a yellow solid.
