Methyl (2-nitrophenyl)acetate (26.6 g, 0.14 mol) and acetic anhydride (51.5 ml, 0.55 mol) were subjected to catalytic hydrogenation for 15 hours in toluene (150 ml) in the presence of 10% Pd/C (53.2% wet, 4.5 g). The reaction mixture was filtered to remove therefrom the catalyst, followed by washing with toluene. The filtrate was distilled under reduced pressure to remove the solvent. The residue was crystallized by the addition thereto of n-hexane and diisopropyl ether. The crystals thus precipitated were collected by filtration, washed with n-hexane, and dried under reduced pressure to give methyl (2-acetamidophenyl)acetate (24.3 g, 84%) as a pale yellow solid.
