Procedure

Ethyl 4-{(1S)-1-[3-[2-fluoro-5-(trifluoromethyl)phenyl]-5-(6-methoxy-2-naphthyl)-1H-pyrazol-1-yl]ethyl}benzoate (2.87 g, 5.11 mmol) was dissolved in MeOH-dioxane (1:2, 60 ml) and treated with NaOH (2.5 g, excess) in water (20 ml). The mixture slowly cleared with stirring, and was left overnight. The reaction mixture was first concentrated to 30 ml, acidified with 2N HCl and extracted with ethyl acetate. The organic layer was washed with brine 2× and dried over Na2SO4. Evaporation of solvent and vacuum drying afforded 4-{(1S)-1-[3-[2-fluoro-5-(trifluoromethyl)phenyl]-5-(6-methoxy-2-naphthyl)-1H-pyrazol-1-yl]ethyl}benzoic acid as colorless dry foam. NMR (500 MHz, CDCl3) δ: 2.00 (d, J=7.0 Hz, 3H); 3.95 (s, 3H); 5.65 (q, J=7.0 Hz, 1H); 6.88 (d, JF-H=4.2 Hz, 1H); 7.17 (d, J=2.5 Hz, 1H); 7.20 (dd, J=2.5 Hz, 8.9 Hz, 1H); 7.26 (t, J=8.6 Hz, 1H); 7.31 (dd, J=1.8 Hz, 8.5 Hz, 1H); 7.32 (d, J=8.4 Hz, 2H); 7.56 (m, 1H); 7.66 (d, J=1.8 Hz, 1H); 7.68 (d, J=8.9 Hz, 1H); 7.77 (d, J=8.5 Hz, 1H); 8.06 (d, J=8.4 Hz, 2H); 8.48 (dd, J=2.9 Hz, 6.9 Hz, 1H). MS C30H22F4N2O3 Cald: 534.16; Obsd (M+1): 535.17.
