Reaction Steps

A solution of 5-fluoro-2-nitrotoluene (1.5 g, 9.6 mmol), N-methylethanolamine (0.90 mL, 0.012 mol) and triethylamine (1.6 mL, 0.012 mol) in N-methyl-2-pyrrolidone (15 mL) was stirred at 60° C. for 12 h. Cooled to ambient temperature, the reaction mixture was poured into ice water, extracted with ethyl acetate. The organic layer was washed with water and brine, dried over sodium sulfate and concentrated to afford 2-[(3-methyl-4-nitrophenyl)-N-methylamino]ethanol as solid (2.0 g, y. 98%).
