Procedure

To a solution of (4S,5R)-4-(3,4-difluorophenyl)-2-oxo-5-(tetrahydropyran-2-yloxymethyl)oxazolidine-3-carboxylic acid {1-[1-(2-cyanophenyl)piperidin-4-yl]-(3R)-pyrrolidin-3-yl}amide (156 mg, 0.26 mmol) in methanol (5 mL) was added p-toluenesulfonic acid (50 mg, 0.26 mmol). The reaction mixture was stirred at room temperature for 17 h. The volatiles were removed under reduced pressure, the residue taken up in ethyl acetate (100 mL), washed with saturated sodium carbonate solution (3×100 mL), brine (1×100 ml), dried over magnesium sulfate and filtered. The volatiles were removed under reduced pressure to afford (4S,5R)-4-(3,4-difluorophenyl)-5-hydroxymethyl-2-oxo-oxazolidine-3-carboxylic acid {1-[1-(2-cyanophenyl)piperidin-4-yl]-(3R)-pyrrolidin-3-yl}amide. The hydrochloride salt was prepared according to standard procedures to provide a white solid (123 mg, 0.22 mmol, 84%)
