Versuchsvorschrift
To a solution of the above ester (0.58 g, 2.29 mmol) in 6 mL of methanol and 0.5 mL of THF was added 2.5 mL of 1 molar sodium hydroxide solution. The solution was stirred for 4 hours at ambient temperature, and then the pH was adjusted to 6 by the addition of 2 M HCl. The reaction mixture was men concentrated under vacuum, and the residue was azeotroped with toluene to provide 4,4-difluorocyclohex-1-ene-1-carboxylic acid an oily solid.
