Reaction Steps

The title compound was obtained as a colorless oil from 1-((E)-3-(benzyloxy)prop-1-enyl)-3,5-difluorobenzene by the same method that is described for Example 39. (4S,5R)-3-(4-(4-chlorophenoxy)phenyl)-5-((benzyloxy)methyl)-4-(3,5-difluorophenyl)oxazolidin-2-one (Example 96) was placed into a 25 mL round bottom flask and dissolved in 7 mL ethanol:ethyl acetate (1:1) and treated with palladium on carbon (10% by weight, 73 mg). The vessel was sealed with a rubber septum and charged with hydrogen. The reaction was stirred for 2 h, then filtered on celite, evaporated to dryness and purified on silica gel (20-30% ethyl acetate/hexanes) to give the title compound as a colorless oil that solidified on standing. 1H NMR (acetone-d6) δ (ppm) 7.53 (d, J=9.1 Hz, 2H), 7.37 (d, J=9.0 Hz, 2H), 7.21-7.16 (m, 2H), d, J=6.15 Hz, 2H), 7.02-6.93 (m, 5H), 5.58 (d, J=5.4 Hz, 1H), 4.55 (t, J=5.8 Hz, 1H), 4.45 (ddd, J=5.6, 3.7, 3.6), 3.97 (ddd, J=12.3, 5.6, 3.8 Hz, 1H), 3.90 (ddd, J=12.3, 5.6, 3.8 Hz, 1H); HPLC-MS calculated C22H16ClF2NO4 (M+H+): 432.1, found: 432.0.
