반응 단계

A solution of 4-nitro-m-cresol (1.4 g, 9.4 mmol), 2-bromoethanol (1.0 mL, 0.014 mol) and potassium carbonate (3.3 g, 0.024 mol) in N,N-dimethylformamide (10 mL) was stirred with heating at 70° C. for 12 h. Cooled to ambient temperature, the reaction mixture was poured into ice water and extracted with ethyl acetate. The organic layer was washed with water and brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by chromatography on silica gel(hexane/ethyl acetate) to afford 2-(3-methyl-4-nitrophenoxy)ethanol as solid (1.3 g, y. 70%).
