Versuchsvorschrift

Crude dimethyl 4-bromo-2-nitrophenylmalonate was heated at 110° C. in 40 mL of 6N hydrochloric acid for 24 hours and then cooled. The precipitate was collected by filtration, washed with water and dried to give 5.3 g (89% yield) of 4-bromo-2-nitrophenylacetic acid as an off white solid.
