Reaction Steps

To a THF (20 ml) solution of (4S,5R)-tert-butyl 4-(fluoromethyl)-2,2-dimethyl-5-(4-((trimethylsilyl)ethynyl)phenyl)oxazolidine-3-carboxylate (1.65 g, 4.1 mmol) that had been cooled to −78° C. (dry ice/acetone) is added tetra-n-butyl-ammonium fluoride (5 ml of 1M solution in tetrahydrofuran, 5 mmol). The reaction is stirred at −78° C. for 1 hour. The reaction mixture is quenched (while at −78° C.) by the addition of saturated aqueous ammonium chloride solution (2 ml). The reaction mixture is warmed to room temperature and diluted with ethyl acetate (50 ml). The organic phase is washed with water (3×25 ml), dried over sodium sulfate and the volatiles removed by evaporation to give the title product (1.35 g).
