Reaction Steps

(4-{5-[1-(2-Chloro-phenyl)-4-trifluoromethyl-1H-imidazol-2-yl]-thiophen-2-yl}-3-methyl-phenyl)-acetic acid methyl ester (123 mg, 0.25 mmol) was dissolved in 6 mL mixture of THF and water (3:1, V/V). Lithium hydroxide monohydrate (2.3 mg, 0.55 mmol) was added then. The mixture was stirred at room temperature for 3 hrs. The mixture was neutralized to pH 7 by 1N HCl, and then extracted with ethyl acetate. The combined organic layers were washed with brine, dried over Na2SO4, and concentrated in vacuo. The crude product was purified by column chromatography on silica gel (0→5% MeOH/DCM) to give a white solid (47 mg, 39% yield). 1H-NMR (400 MHz, CDCl3): δ 2.35 (s, 3H), 3.64 (s, 2H), 6.83 (s, 2H), 7.13-7.10 (m, 1H), 7.16 (m, 1H), 7.29-7.27 (m, 1H), 7.35 (m, 1H), 7.47-7.46 (m, 2H), 7.57-7.52 (m, 1H), 7.64-7.62 (m, 1H). MS (ES): 477.1, [M+H]+
