Procedure

To a solution of (S)-methyl 4-(((4-(trifluoromethyl)phenyl)(3-(trifluoro-methyl)pyridin-2-yl)methyl)carbamoyl)benzoate (135 mg, 0.280 mmol, Example 140) and THF (7 mL):MeOH (3 mL) was added 1M LiOH (1 mL, 1.000 mmol). After 2 h, the reaction was concentrated in vacuo. The off-white solid was taken up in a minimum of DCM and eluted through a Redi-Sep® pre-packed silica gel column (4 g) with EtOAc to provide the title compound as a white solid. 1H NMR (CD3OD, 300 MHz) δ ppm 8.91 (d, J=4.8 Hz, 1H), 8.18 (d, J=7.9 Hz, 1H), 8.03 (d, J=8.3 Hz, 2H), 7.85 (d, J=8.2 Hz, 2H), 7.53-7.66 (m, 5H), 6.93 (s, 1H). MS (ESI pos. ion) m/z: 469.0 (M+H).
