Reaction Steps

To a dioxane (10 ml) solution of (4S,5R)-tert-butyl 4-(fluoromethyl)-2,2-dimethyl-5-(4-(3-((methylsulfonyloxy)methyl)isoxazol-5-yl)phenyl)oxazolidine-3-carboxylate (1.0 g, 2.1 mmol) is added 30% aqueous ammonium hydroxide solution (5 ml). The mixture is stirred at 35° C. for 12 hours. The product is partitioned between water (50 ml) and methylene chloride (25 ml). The organic phase is dried (sodium sulfate) and concentrated to give the title compound (685 mg): m/z (Cl) 406 ([M+H]+.
