A 4.00 g portion of methyl 2,4-dimethoxy-5-nitrobenzoate was dissolved in 200 ml of tetrahydrofuran, and 0.40 g of 10% palladium-carbon was added, followed by stirring for 12 hours at room temperature under normal pressure in an atmosphere of hydrogen. After removing insoluble matter by filtration, the solvent was evaporated under a reduced pressure to give 3.6 g of methyl 5-amino-2,4-dimethoxybenzoate.
