To a solution of (4-{3-[3-(4-chloro-phenylethynyl)-5-(3-morpholin-4-yl-prop-1-ynyl)-phenyl]-prop-2-ynyloxy}-2-methyl-phenoxy)-acetic acid methyl ester (63 mg, 0.11 mmol) in THF (1.25 ml) and methanol (0.25 ml) was added a ice-cold solution of LiOH (1 M, 1.25 ml). The reaction mixture was stirred at 0° C. for 460 min., after which water (10 ml) and aqueous HCl (1M, 1.75 ml) were added. The mixture was extracted with ethyl acetate (2×10 ml), and the combined organic phases were dried and evaporated to give the title compound in 29 mg (48%) yield.
