Reaction Steps

{2-Methyl-4-[3-(3-morpholin-4-yl-prop-1-ynyl)-5-(5-trifluoromethyl-pyridin-2-yloxy)-phenylsulfanyl]-phenoxy}-acetic acid ethyl ester (262 mg; 0.45 mmol) was dissolved in ethanol (15 mL), and aqueous 1 N sodium hydroxide (3 mL) was added. The reaction mixture was stirred for 16 h. acidified with 1 N aqueous hydrochloric acid and extracted with ethyl acetate, dried and evaporated to dryness. The organic phase was purified by preparative HPLC (method B). Yield: 174 mg (68%). HPLC-MS: m/z: 559.5 (M+H)+; Rt: 1.81 min.
