Versuchsvorschrift

Into a 50-mL round-bottom flask, was placed 2-bromophenol (5.1 g, 29.48 mmol, 1.00 equiv), 2-bromoacetonitrile (5.3 g, 44.19 mmol, 1.50 equiv), potassium carbonate (8 g, 57.97 mmol, 2.00 equiv), N,N-dimethylformamide (20 mL). The resulting solution was stirred overnight at 60° C. in an oil bath. The resulting solution was diluted with 5×50 mL of EA. The organic layer was washed with 50 mL of H2O. Organic layers were collected and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:100). This resulted in 6 g (96%) of 2-(2-bromophenoxy)acetonitrile as a brown solid.
