Methyl 2-ethoxy-4-nitrobenzoate → Methyl 4-amino-2-ethoxybenzoate

Participants

Reaction Steps

A mixture of methyl 2-ethoxy-4-nitrobenzoate (2.038 g, 9.05 mmol) and palladium on carbon (583 mg, 10 wt %, Aldrich) in methanol (62 ml) was reacted with hydrogen at 40 psi for 18 hrs on the PARR shaker. It was filtered through celite and washed with methanol under N2 and the filtrate was concentrated to give methyl 4-amino-2-ethoxybenzoate (1.672 g, 94%) as a light brown solid.
