Reaction Steps
Add sodium hydroxide (5.0N, 0.09 mL, 0.42 mmol) to 3-fluoro-4-{1-[6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-heptyloxy}-benzoic acid methyl ester (0.04 g, 0.085 mmol) in methanol (2 mL). Add tetrahydro-furan (1 ml) and stir for four hours. Acidify with 1.0 N HCl and extract desired compound with ethyl acetate three times. Dry organic fractions with Na2SO4, filter and concentrate under reduced pressure to provide 0.035 g (90%) of title compound.
