Versuchsvorschrift

257 mg 95% sodium hydride were stirred at room temperature in 25 ml dry DMF under an atmosphere of nitrogen. A solution of 1 g 3-bromophenylacetonitrile and 1.593 g iodomethane in 10 ml dry diethyl ether was added slowly below 30° C. The mixture was stirred over night at room temperature and then quenched by addition of a small amount of water. The solvents were evaporated under vacuum and the residue was purified by chromatography on silica in a heptane/ethyl acetate gradient.
