Procedure
To a solution of the crude product from Step F (ca 1.68 mmol) in 25 mL of 1:1 MeOH/EtOAc was added trifluoroacetic acid (0.10 mL) and 10% palladium on carbon (800 mg). The solution was stirred under a balloon atmosphere of hydrogen at room temperature. After 4 hours, the solution was filtered through celite, the filter pad was rinsed with 1:1 MeOH/THF, and the filtrate was concentrated in vacuo. The crude material containing the titled product was used in the next reaction without further purification.
