A solution of racemic [1-Azido-3-methoxy-2-cyclohexanoxy]tert-butyl-dimethylsilane, 51g, (2.57 g; 6.3 mmol) in 20 mL of ethyl acetate was hydrogenated with Pd—C 10% (5 mole %; Degussa) at 45 PSI in a Parr hydrogenation apparatus for 1 h. The reaction mixture was filtered over a nylon and glass fiber filter and concentrated in vacuo to provide 2.32 g of the desired product 51h as a white solid.
