Versuchsvorschrift

10.5 g (38.6 mmol) of 3-(4-bromo-3-fluoro-phenyl)-acrylic acid ethyl ester were dissolved in 100 mL of methanol and stirred overnight with 97 mL of aqueous 1 M sodium hydroxide solution. After removal of the methanol in vacuo the residue was acidified with concentrated hydrochloric acid. The precipitate was isolated by suction and dried in vacuo at 50° C. furnishing 8.0 g of 3-(4-bromo-3-fluoro-phenyl)-acrylic acid.
