Reaction Steps

A mixture of ethyl 2-(5-chloro-6-(2,2,2-trifluoroethoxy)-4′-(trifluoromethyl)biphenyl-3-yl)-3-(4-fluorophenyl)propanoate (400 mg, 0.719 mmol) and lithium hydroxide monohydrate (0.306 g, 7.29 mmol) in a MeOH/THF/Water solvent mixture (10 ml/10 ml/10 ml) was stirred for 3 h at room temperature. After completion of reaction volatiles were removed under reduced pressure. The residue was diluted with water, acidified with 5% HCl solution and extracted with ethyl acetate (3×50 mL). The combined organic layers were washed with water, dried over Na2SO4, filtered and evaporated under reduced pressure. The residue was purified by Flash Column Chromatography to give 2-(5-chloro-6-(2,2,2-trifluoroethoxy)-4′-(trifluoromethyl)biphenyl-3-yl)-3-(4-fluorophenyl)propanoic acid (0.1 g). 1H-NMR (CDCl3, 400 MHz): 7.55-7.78 (m, 4H); 7.42 (s, 1H), 7.18 (s, 1H); 6.92-7.16 (m, 4H); 3.98 (q, 2H); 3.84 (t, 1H); 3.41 (dd, 1H), 3.02 (dd, 1H).
