Procedure

2-Methyl-2-{4-[2-(5-methyl-2-phenyl-oxazol-4-yl)ethylsulfanyl]phenoxy}propionic acid ethyl ester (98 mg, 0.23 mmol) was dissolved in EtOH (10 mL) and 5N NaOH (0.5 mL) was added. The reaction was stirred overnight at rt. The reaction was acidified with 5N HCl and the product was extracted into EtOAc, dried (MgSO4) and concentrated to give 96 mg crude product. Purification by reverse phase HPCL gave 47.5 mg (52%) as a light tan solid: mp 104-106° C., 1H NMR (DMSO-d6) δ 1.47 (s, 6H), 2.26 (s, 3H), 2.71 (t, 2H), 3.16 (t, 2H), 6.78 (d, 2H), 7.30 (d, 2H), 7.48 (m, 3H), 7.90 (m, 2H), 13.08 (br s, 1H).
