Reaction Steps

The required 1-(2-methoxy-ethoxy)-3-methyl-2-nitrobenzene was prepared from 3-methyl-2-nitrophenol. To a stirred solution of the phenol (2.0 g, 13.1 mmol) in DMF (65 mL) was added potassium carbonate (2.16 g, 15.7 mmol) and bromoethyl methyl ether (1.47 mL, 15.7 mmol) at room temperature. After the mixture was stirred at 50° C. for 48 h, water was added. The mixture was extracted with EtOAc (3×), washed with brine, dried over anhydrous MgSO4 filtered and evaporated. After chromatographic purification on silica gel, 1-(2-methoxy-ethoxy)-3-methyl-2-nitrobenzene was obtained in 85% yield (2.34 g). 1H NMR (500 MHz, CDCl3) δ 7.28 (1H, t, J=8.0 Hz), 6.89 (1H, d, J=9.0 Hz), 6.85 (1H, d, J=8.0 Hz), 4.19 (2H, t, J=4.5 Hz), 3.72 (2H, t, J=5.0 Hz), 3.41 (3H, s), 2.30 (3H, s).
