Procedure

A solution of diethyl azodicarboxylate (0.56 mL, 3.6 mmol) in anhydrous THF (3.0 mL) was added drop-wise to a mixture of (1R,2R,4R)-5,5-difluorobicyclo[2.2.1]heptan-2-ol (0.44 g, 3.0 mmol), phthalimide (0.50 g, 3.4 mmol), and triphenyl phosphine (0.78 mL, 3.4 mmol) in anhydrous tetrahydrofuran (15.0 mL) at r.t. under nitrogen. After stirring at ambient temperature for 66 h, the solvents were removed in vacuo. The residue was partitioned between ethyl acetate and water, and the organic portion was separated, washed with brine, and conc. in vacuo. Flash column chromatography (0 to 35% of ethyl acetate in hexanes) gave the title compound as an off-white solid.
