Reaktionsschritte

To 2-(4-fluorophenyl)-2-[(trimethylsilyl)oxy]acetonitrile (0.500 g, 2.24 mmol) in degassed THF (11 ml) at −78° C. was added LHMDS 1M in THF (2.4 ml). To the previous reaction mixture a solution of methyl 4-(bromomethyl)benzoate (0.513 g, 2.25 mmol) in THF (2 ml) was then added. After a period of 1 h at r.t., tetrabutylammonium fluoride solution 1 M in THF (2.23 ml) was added to the reaction mixture and stirred for 10 minutes. Water was added and the mixture was extracted with ethyl acetate. The organic phase was dried over sodium sulfate and evaporated to dryness. The residue was purified by flash chromatography using hexane/ethyl acetate 30% giving 0.4 g of the title compound.
