Procedure

Palladium (10 wt. % on activated carbon, 0.28 g) was added to a solution of (1R,4R,5S)-5-(benzyloxy)-2,2-difluorobicyclo[2.2.1]-heptane (1.43 g, 6.0 mmol) in methanol (15 mL), and the mixture was placed under a balloon full of hydrogen. After stirring at ambient temperature for 4 h, the mixture was filtered through a pad of Celite, and the filtrate was concentrated in vacuo. The residue was adsorbed onto a small pad of silica gel, and eluted with 20% of ethyl acetate in hexanes. The solvents were removed in vacuo to give the title compound as a white solid.
