To a stirred solution of (5-{4-[(1R,2S)-2-(2,2-Dichloro-acetylamino)-3-fluoro-1-hydroxy-propyl]-phenyl}-oxazol-2-ylmethyl)-carbamic acid tert-butyl ester (0.006 g, 0.012 mmol) in CH2Cl2 (1.0 mL) is added trifluoroacetic acid (0.1 mL) at 0° C. and stirred at room temperature for 2 hours. Reaction mixture is concentrated in vacuum and the residue is washed with n-pentane dried under vacuum to give the title compound (0.005 g). 1H-NMR (400 MHz, DMSO-d6) δ: 4.22-4.28 (m, 1.5H), 4.31 (s, 2H), 4.40-4.44 (m, 0.5H), 4.56-4.60 (m, 0.5H), 4.68-4.71 (m, 0.5H), 4.89 (m, 1H), 6.02 (d, J=4.28 Hz, 1H), 6.49 (s, 1H), 7.47 (d, J=8.16 Hz, 2H), 7.67 (d, J=8.2 Hz, 2H), 7.72 (s, 1H), 8.21 (bs, 3H), 8.60 (d, J=8.88 Hz, 1H). LC-MS (m/z): [M+H]=376.1.
