実験手順

To a stirred solution of ethylamine (2.0M solution in tetrahydrofuran; 0.31 mL, 0.027 mmol) in tetrahydrofuran (5 mL) is added methanesulfonic acid 5-{4-[(4S,5R)-3-(2,2-difluoro-acetyl)-4-fluoromethyl-2,2-dimethyl-oxazolidin-5-yl]-phenyl}-pyridin-2-ylmethyl ester (0.1 g, 0.212 mmol) at room temperature then stirred overnight. Solvent is evaporated in vacuo. The crude material is purified by combi-flash chromatography using 10% methanol in CH2Cl2 as an eluent to afford the title compound (0.062 g). 1H-NMR (400 MHz, DMSO-d6) δ: 1.09 (t, J=7.12 Hz, 3H), 1.52 (s, 3H), 1.60 (S, 3H), 2.66-2.71 (q, 2H), 3.96 (s, 2H), 4.51-4.56 (m, 0.5H), 4.57-4.58 (m, 1H), 4.59-4.69 (m, 0.5H), 4.70-4.82 (m, 1H), 5.27 (d, J=3.56 Hz, 1H), 6.64 (t, J=52.4 Hz, 1H), 7.53 (d, J=8.2 Hz, 1H), 7.60 (d, J=8.12 Hz, 2H), 7.79 (d, J=8.2 Hz, 2H), 8.09-8.11 (dd, J1=2.28 Hz, J2=8.08 Hz, 1H), 8.86 (d, J=2.08 Hz, 1H). LC-MS (m/z): [M+H]=422.
