Procedure

A solution of azide, 50d, (0.25 g; 0.89 mmol) in 20 mL of ethyl acetate was hydrogenated with Degussa palladium (20 mole %) under 1 atmosphere of hydrogen overnight. The reaction mixture was filtered over celite and the celite was eluted with 2×10 mL of EtOAc. The filtrate was concentrated in vacuo to afford 230 mg of an oil that was used directly for the next step without further purification.
