The reaction mixture was stirred for 1 h at 0° C. and then poured into 1N hydrochloric acid solution. The mixture was extracted with ethyl acetate (30 mL) then the separated organic phase was washed with water (2×30 mL), brine (25 mL), dried over anhydrous sodium sulfate and concentrated in vacuo to afford 2-(2-methoxy-6-nitro-phenyl)-ethanol (780 mg, 94%).
