Versuchsvorschrift
A mixture of 3-fluorophenol (11.2 g, 100 mmol), 2-bromoacetamide (13.8 g, 100 mmol), K2CO3 (13.82 g, 100 mmol) and Cs2CO3 (32.58 g, 100 mmol) in acetone (150 mL) was refluxed overnight. The mixture was cooled to rt and filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=1:1) to give the title compound as a white solid (5.06 g, 30%).
