Hydrochloric Acid → 3-(4-{2-[4-Isopropyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-propoxy}-2-methyl-phenyl)-propionic Acid

Participants

Reaction Steps

3-(4-{2-[4-Isopropyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-propoxy}-2-methyl-phenyl)-propionic acid methyl ester (239 mg, 0.4725 mmol) is dissolved in tetrahydrofuran (1 mL) and 5N NaOH (1 mL) is added. The mixture is heated to reflux until the conversion is complete. Upon complete conversion, the reaction is cooled to room temperature and 5N HCl (1 mL) is added. The mixture is diluted with diethyl ether and extracted with 1N HCl. The organic layer is washed with water and brine, then dried over anhydrous sodium sulfate. Concentration of the solvent reveals the pure 3-(4-{2-[4-Isopropyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-propoxy}-2-methyl-phenyl)-propionic acid in near quantitative yield (221 mg, 0.4489 mmol).
