Procedure
17.3 g KOtBu was dissolved in 500 mL THF and 9 mL acetophenone was added. After 15 min at RT 25.9 g 4-fluoro-3-methyl-benzoic acid methyl ester was added and stirred for 3 h at RT. The solvent was removed and the residue was purified by chromatography on silica gel (cyclohexane/EE: 98:2) to yielded 19.3 g of the desired compound.
