To a mixture of 158d (11.0 g, 42 mmol) in ethanol/water (150 mL/100 mL) was added lithium hydroxide (8.8 g, 210 mmol). See FIG. 4. The resulting mixture was stirred at 15° C. for 2 h. The mixture was diluted with water and extracted with EtOAc (200 mL×3). The organic layers were dried over anhydrous sodium sulfate and concentrated to afford 3-(3-(trifluoromethoxy)phenyl)propanoic acid 158e as a colorless oil.
