A 25 mL round bottomed flask was charged with 2-{2-methoxymethyl-4-[2-(5-methyl-2-phenyloxazol-4-yl)ethoxy]phenoxy}-2-methylpropionic acid ethyl ester (0.039 g, 0.087 mmol), ethanol (2 mL), and then aqueous 2N NaOH (0.22 mL, 0.44 mmol). The solution was heated at 55° C. for 1 h. The mixture was concentrated, acidified using 5% H2SO4 (1.5 mL), and partitioned between CH2Cl2 (15 mL) and brine (15 mL). The organic layer was dried (Na2SO4), filtered, and concentrated and to give a white solid (0.024 g, 66%). MS (ES) m/e 426 (M+1).
