Procedure

A mixture of 4-chloro-3-nitrophenol (25 g), N,N-dimethylformamide (200 mL), potassium carbonate (60 g) and bromoacetic acid methyl ester (15.5 mL) was stirred at room temperature for 2.5 hours. The mixture was partitioned between ethyl acetate and water, and the aqueous phase extracted with ethyl acetate. The combined extracts were dried over sodium sulfate and then concentrated under reduced pressure. The residue was washed with diethyl ether to afford title compound as a white solid (30 g).
