To a stirred solution of (4S,5R)-4-Fluoromethyl-5-{4-[2-(methanesulfonylamino-methyl)-imidazo[1,2-a]pyridin-7-yl]-phenyl}-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (75 mg, 0.14 mmol) in CH2Cl2 (1 mL) is added trifluoroacetic acid (0.3 mL) drop wise at 0° C. then stirred at room temperature for 2 hours. The reaction mixture is concentrated and stripped with CH2Cl2 to afford title compound (88 mg, crude) which is used as is in the next step. LC-MS (m/z): [M+H]=393.1.
