2-(2-bromophenoxy)ethanamine

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Into a 8-mL pressure tank reactor, was placed methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv), 2-(2-bromophenoxy)ethanamine (750 mg, 1.74 mmol, 3.98 equiv, 50%), n-BuOH (2 mL). The resulting solution was stirred overnight at 100° C. in an oil bath. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with PE/EA (10:1). This resulted in 163.9 mg (crude) of methyl 3-(2-(2-bromophenoxy)ethylamino)-2-phenylquinoxaline-6-carboxylate as a yellow solid. Into a 8-mL pressure tank reactor, was placed The resulting mixture was concentrated under vacuum This resulted in 163.9 mg (crude) of methyl 3-(2-(2-bromophenoxy)ethylamino)-2-phenylquinoxaline-6-carboxylate as a yellow solid

Procedure: 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.
