Methyl 3-(difluoromethoxy)-4-nitrobenzoate (0.9 g) was placed in a 250 mL round bottom flask and dissolved in 30 mL of ethanol. Pd/C (0.15 g, 10% Pd) was carefully added and a balloon of hydrogen was attached to the flask. The reaction was vigorously stirred over night. After checking by TLC, the reaction was filtered through a pad of celite and concentrated to give 0.6 g of methyl 4-amino-3-(difluoromethoxy)benzoate which was used without further purification.
