Reaction Steps
5-bromo-2-fluoronitrobenzene (5.0 g, 22.7 mmol), 2-(methylamino)ethanol (4.26 g, 56.8 mmol) and K2CO3 (9.4 g, 68.1 mmol) in DMF (20 mL) was heated to 60° C. for 1.5 hours, cooled to rt, diluted with water and extracted with EtOAc. The organic phases were washed with water, brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to provide 6.98 g (100%) of the desired product 2-((4-bromo-2-nitrophenyl)(methyl)amino)ethanol (251): 1H NMR (300 MHz, CDCl3) δ 7.87 (1H, d), 7.51 (1H, dd), 7.10 (1H, d), 3.77 (2H, t), 3.39 (2H, t), 2.83 (3H, s).
