Versuchsvorschrift

To methyl 5-(2-methoxyethoxy)-2-nitrobenzoate (1.08 g, 4.2 mmol) under argon was added 10% Palladium on carbon and MeOH (20 mL). The flask was flushed with H2(g) and stirred under H2 (1 atm) for 30 minutes. The mixture was filtered through Celite and concentrated in vacuo to give methyl 2-amino-5-(2-methoxyethoxyl)benzoate (964 mg, 4.2 mmol, 100%). LC-MS (ESI) m/z 226 (M+H)+.
