Procedure

To a flask containing ethyl 3-(4-(1-(3-methoxy-5-methyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenoxy)butyl)benzamido)propanoate (37.0 mg, 0.0700 mmol) was added tetrahydrofuran (0.170 mL), methanol (0.170 mL), and 1 N sodium hydroxide (0.170 mL, 0.170 mmol) was then added. The suspension was stirred at room temperature for 18 hours. The reaction was quenched with 1 N hydrochloric acid to pH 2 and extracted three times with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered, and concentrated to give crude material. The crude material was azeotrophed three times with methylene chloride and then dried in vacuo for 18 h to provide (+/−)-3-(4-(1-(3-methoxy-5-methyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenoxy)butyl)benzamido)propanoic acid (26.0 mg, 74%) as a solid. 1H NMR (400 MHz, CDCl3) δ 7.87 (s, 1H), 7.73 (d, J=8.4 Hz, 2H), 7.66 (s, 1H), 7.39 (d, J=8.2 Hz, 2H), 6.88 (t, J=6.0 Hz, 1H), 6.41-6.21 (m, 2H), 5.17 (dd, J=7.7, 5.2 Hz, 1H), 3.75-3.65 (m, 2H), 3.63 (s, 3H), 2.66 (t, J=5.9 Hz, 2H), 2.04-1.93 (m, 1H), 1.89 (s, 3H), 1.86-1.74 (m, 1H), 1.62-1.35 (m, 2H), 0.96 (t, J=7.4 Hz, 3H). MS (M+1): 520.4.
