Versuchsvorschrift

(5-Chloro-2-nitrophenyl)acetonitrile was prepared from 4-chloronitrobenzene and 4-chlorophenoxyacetonitrile according to procedure known in the art (M. Makosza, J. Winiarski, J. Org. Chem. 1984, 49, 1494). To a suspension of 13.8 g (0.1 mol) anhydrous potassium carbonate in 100 ml acetonitrile were added 100 mg 18-crown-6, 3.93 g (20.0 mmol) of (5-chloro-2-nitrophenyl)acetonitrile, and 4.15 g (21.95 mmol) 3-fluorobenzyl bromide, successively. It was stirred at room temperature overnight, and the solids were removed by filtration. The filtrate was concentrated under reduced pressure, and the residue was stirred with a small amount of ethanol to give the pale yellow crystalline title compound, which was collected by filtration, washed with cold ethanol, and dried in vacuo.
