Reaction Steps

A solution of methyl 4-carboxy-3-nitrobenzoate (3 g, 13.3 mM) in ethanol (20 ml) was hydrogenated at atmospheric pressure in the presence of 10% palladium-carbon (1 g) for 40 minutes. After filtration of the catalyst, the solid was recrystallised from ethanol to give methyl 3-amino-4-carboxybenzoate (1.7 g, 65%).
