Reaktionsschritte

9.27 g KOtBu was added to 109 mg 18-Krone-6 and 5 mL 4-fluoracetophenone in 150 mL THF. After 30 min at RT 10.7 g 4-fluoro-benzoic acid methyl ester was added and stirred for 3 h at RT. The reaction was decomposed with water and filtered, the filtrate was concentrated and the residue was purified by chromatography on silica gel (cyclohexane/EE: 98:2). The solvent was removed and 3.9 g of the desired compound was obtained.
