Procedure
{4-[3-[2-(4-Chloro-phenyl)-ethoxy]-5-(4-methanesulfonyl-phenylethynyl)-phenylsulfanyl]-2-methyl-phenoxy}-acetic acid ethyl ester (190 mg; 0.30 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. The organic phase was dried and evaporated to dryness and purified by prep HPLC (method B). Yield: 160 mg (89%). HPLC-MS: m/z: 607.1 (M+H)+; Rt: 2.82 min.
