Procedure

A solution of 1-(4-Fluoro-phenyl)-5-trifluoromethyl-1H-pyrazole-4-carboxylic acid (0.300 g, 1.097 mmol, prepared in example 635) in DMF (4.0 mL) was reacted with (2S)-amino-3-(4′-trifluoromethyl-biphenyl-4-yl)propionic acid methyl ester Hydrochloride (0.394 g, 1.097 mmol), HBTU (0.416 g, 1.097 mmol), and DIEA (0.585 mL, 3.29 mmol) as described in general procedure A. The crude compound was purified by washing with ethyl ether to give 0.300 g (47%) of 2-{[1-(4-Fluoro-phenyl)-5-trifluoromethyl-1H-pyrazole-4-carbonyl]-amino}-3-(4′-trifluoromethyl-biphenyl-4-yl)-propionic acid methyl ester. A solution of this ester (0.125 g, 0.215 mmol) in THF (4.0 mL) was treated with LiOH (0.031 g) by general procedure I to afford (0.105 g, 87%) the title compound 2-{[1-(4-Fluoro-phenyl)-5-trifluoromethyl-1H-pyrazole-4-carbonyl]-amino}-3-(4′-trifluoromethyl-biphenyl-4-yl)-propionic acid as a white solid. LCMS: 565 (M+1)+. 1H NMR (DMSO-d6) 8.92 [d, 1H], 8.39 [s, 1H], 8.18 [d, 2H], 8.09 [d, 2H], 7.96 [d, 2H], 7.87 [m, 2H], 7.71 [m, 4H], 4.83 [m, 1H], 3.58 [m, 1H], 3.36 [m, 1H].
