A solution of 4S,5R)-5-(3,5-bis(trifluoromethyl)phenyl)-3-((4′-fluoro-5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl)methyl)-4-methyl-1,3-oxazolidin-2-one (54) [prepared by methods described in WO2007/005572] (1.4 g) in DCM (5 mL) was treated with BBr3 (0.9 mL) at 15-16° C. and the reaction mixture stirred for 1 hr. The mixture was quenched with ice and diluted with EtOAc (150 mL) The mixture was washed with water, sat'd NaHCO3 solution, and brine, dried (Na2SO4), filtered and the solvent concentrated under reduced pressure. The crude product was purified by chromatography on silica gel to give 1.01 g (60%) of 55. 1H NMR (CDCl3) δ: 7.85 (s, 1H), 7.75-7.62 (m, 4H), 7.42 (m, 1H), 6.96 (dd, 1H), 7.69 (dd, 1H), 5.64 (d, 0.5H), 5.39 (d, 0.5H), 4.92-4.80 (m, 1H), 4.18 (d, 0.5H), 3.99 (d, 0.5H), 3.85 (m, 0.5H), 3.75 (m, 0.5H), 3.19 (m, 1H), 1.17-1.25 (m, 6H), 0.57 (d, 1.5H), 0.45 (d, 1.5H).
