Procedure

To a vigorously stirred suspension of (2R,3S)-5-methylene-3-nitro-2-(2,4,5-trifluorophenyl)tetrahydro-2H-pyran (200 mg, 0.73 mmol) and zinc powder (561 mg, 8.59 mmol) in ethanol (7 mL) was added 6N hydrochloric acid (2.3 mL, 14 mmol). After one hour, the mixture was treated with ether (100 mL) and aqueous sodium hydroxide solution (2.5N, 40 mL). The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate and evaporated to yield (2R,3S)-5-methylene-2-(2,4,5-trifluorophenyl)tetrahydro-2H-pyran-3-amine which was used in the next step without further purification.
