HCl (4.0 M in 1,4-dioxane, 1.0 mL) was added to a solution of (2R)-4-{4′-[(5R)-5-(acetamidomethyl)-2-oxo-1,3-oxazolidin-3-yl]-2′-fluorobiphenyl-4-yl}-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (50 mg, 0.083 mmol) in 1,4 dioxane/dichloromethane/water (1:1:1, 3 mL). After 15 minutes reaction was concentrated to give a white solid. The solid was triturated with a mixture of diethyl ether/2-propanol (10:1, 10 mL) for 2 hours. The title compound was collected as a white solid (16 mg, 37%) by filtration.
