Reaction Steps

To a stirred solution of ethyl fluoroacetate (0.59 ml; 6.0 mmol) in tetrahydrofuran (6 ml) under nitrogen at −76° C. was added dropwise a 0.5 M solution of 4-chlorophenethylmagnesium bromide in tetrahydrofuran (10 ml; 5.0 mmol). The suspension obtained was stirred at −50° C. during 5 h. The mixture was poured in ammonium chloride sat. solution (20 ml) and extracted with dichloromethane (3×20 ml). Combined organics were dried over sodium sulfate and evaporated. The crude obtained was subject flash chromatography (eluant: c-hexane/ethyl acetate 95:5) to afford 0.13 g (18% of theory) of 4-(4-chloro-phenyl)-1-fluoro-butan-2-one as a yellow oil.
