Versuchsvorschrift
A mixture of methyl 2-methoxy-4-(N-methylacetamido)-5-nitrobenzoate (2.1 g; 0.74 mmol), aqueous NaOH (29 mL; 1 M; 29 mmol) and EtOH (30 mL) was refluxed for 2 h. The mixture was thereafter concentrated and the remaining aqueous phase was acidified to strongly acidic pH with acetic acid, sonicated and filtered to give the sub-title compound.
