Procedure

To a solution of the above ester (4.11 mmol, 0.811 g) in 95% ethanol (50 mL) was added platinum (IV) oxide (0.354 mmol, 0.081 g), and the reaction was pressurized to 50 psi of H2. The reaction was stirred vigorously for 12 hours. The reaction was filtered through a pad of celite and the celite was washed with portions of ethyl acetate. The solvents were removed under reduced pressure to provide acetic acid (3S,6R)-3-hydroxy-8-methyl-8-aza-bicyclo[3.2.1]oct-6-yl ester (0.98 g) which was used without further purification in the next step.
