Reaction Steps

{4-[3-Isobutoxy-5-(3-morpholin-4-yl-prop-1-ynyl)-phenoxy]-2-methyl-phenoxy}-acetic acid ethyl ester (260 mg; 0.56 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: 180 mg; 72%.
