Versuchsvorschrift
A solution of 6-chloro-2-nitrophenol (1.7 g.) and ethyl chloroacetate (2.1 ml.) in dimethylformamide (12 ml.) with potassium carbonate (1.5 g.) was stirred at 75°-80° C. for 3 hours. The mixture as poured into water (120 ml.) and extracted with ethyl acetate (4× 50 ml.). The organic layer on evaporation yielded 6-chloro-2-nitrophenoxyacetic acid ethyl ester as a yellow oil.
