Versuchsvorschrift
A solution of 2-(5-bromo-3-methoxycarbonyl-phenoxy)-acetic acid tert-butyl ester (12.8 g) in a mixture of dichloromethane (100 ml) and trifluoroacetic acid (100 ml) was stored at room temperature for 2 h. The solution was concentrated under reduced pressure. The residual solid was suspended in toluene and the solvent removed under reduced pressure to give the title compound as a brown solid (10.6 g).
