Procedure

To a solution of (5-{4-[(1R,2S)-2-(2,2-Dichloro -acetylamino)-3-fluoro-1-hydroxy-propyl]-phenyl}-pyridin-2-ylmethyl)-(3-methyl-butyl)-carbamic acid tert-butyl ester (8 mg, 0.014 mmol) in dry CH2Cl2 (0.04 mL) is added trifluoroacetic acid (0.04 mL) and resulting reaction mixture is stirred at room temperature for 2 hours. Solvent is evaporated in vacuo to get brown crude, which is washed with diethyl ether: pentane (1:9), to give the title compound (8 mg): 1H-NMR (400 MHz, DMSO-d6) δ 0.89 (d, 6H, J=6.40 Hz), 1.52-1.58 (m, 2H), 1.60-1.65 (m, 1H), 3.01 (bs, 1H), 4.20-4.23 (m, 2H), 4.29-4.31 (m, 0.5H), 4.36-4.38 (m, 2H), 4.40-4.44 (m, 0.5H), 4.57-4.59 (m, 0.5H), 4.70-4.71 (m, 0.5H), 4.91-4.93 (m, 1H), 6.02 (d, 1H, J=4.28 Hz), 6.52 (s, 1H), 7.49 (d, 2H, J=8.24), 7.57 (d, 1H, J=8.16 Hz), 7.73 (d, 2H, J=8.28 Hz), 8.19 (dd, 1H, J1=8.16 Hz, J2=2.32 Hz), 8.65 (d, 1H, J=8.96 Hz), 8.96 (d, 1H, J=1.96 Hz), 9.00 (bs, 2H). LC-MS (m/z): [M+H]=456.1.
