Procedure

{2′-[((1S,2R)-2-Hydroxy-1-methyl-2-phenyl-ethylamino)-methyl]-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl}-acetic acid methyl ester (0.021 g, 0.04 mmol) in MeOH (0.33 mL) and THY (0.4 mL) was treated with IN aqueous NaOH (0.1 mL) and stirred at room temperature for 4 hours. Analytical LCMS showed that some starting material was still present, so additional 1N aqueous NaOH (0.05 mL) was added, and the reaction was stirred at room temperature overnight. Analytical LCMS showed that starting material still remained, so additional 1N aqueous NaOH (0.1 mL) was added, and the reaction was stirred for 4 hours. After work-up with CH2Cl2 and 1N aqueous HCl, the combined organic layers were dried over MgSO4, filtered, and concentrated to give the title compound.
