2-(2-bromophenoxy)acetonitrile

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Into a 500-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 2-(2-bromophenoxy)acetonitrile (5.63 g, 26.68 mmol, 1.00 equiv) in tetrahydrofuran (20 mL). This was followed by the addition of BH3 in tetrahydrofuran (143 mL, 5.30 equiv) dropwise with stirring at 0° C. The resulting solution was stirred overnight at 20° C. in an oil bath and quenched by the addition of water (10 ml). The resulting mixture was concentrated under vacuum and diluted with water. The pH value of the aqueous solution was adjusted to 10 with 1N sodium hydroxide and extracted with 6×50 mL of dichloromethane. The organic layers was combined and concentrated under vacuum. This resulted in 5.67 g (crude) of 2-(2-bromophenoxy)ethanamine as pale brown oil.

実験手順: 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. Into a 50-mL round-bottom flask, was placed The organic layer was washed with 50 mL of H2O Organic layers were collected concentrated under vacuum This resulted in 6 g (96%) of 2-(2-bromophenoxy)acetonitrile as a brown solid
