Participants

Reaction Steps

{2-Methyl-4-[3-(3-morpholin-4-yl-propoxy)-5-phenylethynyl-phenylsulfanyl]-phenoxy}-acetic acid ethyl ester (150 mg; 0.28 mmol) was dissolved in ethanol (15 mL), and aqueous 1N sodium hydroxide (3 mL) was added. The reaction mixture was stirred for 16 h, acidified with 1N aqueous hydrochloric acid, and extracted with ethyl acetate. The organic phase was dried and evaporated to dryness. Yield: 110 mg. HPLC-MS: m/z: 518.1 (M+H); Rt: 1.86 min.
