Procedure

3.1 g of iron powder was added to a mixed solution of 24 mL of methanol and 24 mL of acetic acid containing 4.8 g of methyl 2-nitro-4-phenylbenzoate, and the resulting mixture was heated to reflux for 2 hours. After the reaction mixture was cooled to room temperature, insoluble were removed by filtration and a saturated sodium hydrogen carbonate aqueous solution and ethyl acetate added to the filtrate. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium hydrogen carbonate aqueous solution and a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure, Hexane was added to the obtained residue and a solid substance was separated by filtration to obtain 1.8 g of methyl 2-amino-4-phenylbenzoate as white solid.
