Reaction Steps

To a solution of 4.856 g of N-[2-(4-bromo-2-nitrophenyl)ethyl]-2,2,2-trifluoroacetamide in 56 mL of methanol was added 3.417 mL of 5 mol/L sodium hydroxide solution. After being stirred at room temperature overnight, and at 50° C. overnight, the reaction mixture was concentrated under reduced pressure. To the residue were added ethyl acetate and water, and the mixture was separated. After the aqueous layer was extracted with ethyl acetate, the organic layers were combined, and washed with brine. After the organic layer was dried over anhydrous magnesium sulfate, the solvent was removed under reduced pressure to give 3.44 g of 2-(4-bromo-2-nitrophenyl)ethylamine.
