Procedure
To methyl 3′-[2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-6-(1H-pyrazol-1-yl)pyridin-3-yl]-4′-methoxy-2-methylbiphenyl-4-carboxylate (91.4 mg, 0.126 mmol) in dioxanes (2 mL) was added lithium hydroxide (0.5 M, 1.0 mL, 0.505 mmol). The system was heated to 40° C. and was stirred for 1.5 hrs. The reaction was cooled to room temperature and TFA (100 μL) was added to the reaction before volatiles were removed. The crude material was purified by reverse phase HPLC to yield 3′-[2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-6-(1H-pyrazol-1-yl)pyridin-3-yl]-4′-methoxy-2-methylbiphenyl-4-carboxylic acid (86.1 mg, 0.104 mmol). LCMS calc.=711.2. found=711.2. 1H NMR (CD3OD, 500 MHz) δ 8.62 (s, 1H), 7.88 (m, 8H), 7.34 (m, 4H), 6.56 (s, 1H), 5.81 (m, 1H), 4.84 (m, 1H), 4.24 (m, 2H), 3.90 (br s, 3H), 3.36 (br s, 3H), 0.67 (d, J=33.5 Hz, 3H).
