Procedure

Part 1. To a solution of methyl 4-[(tert-butoxy)carbonylamino]-3-nitrobenzoate (0.44 g, 1.5 mmol) in methanol (2 mL), ethyl acetate (3 mL) and triethylamine (0.21 mL, 1.5 mmol) was added 10% Pd on carbon (159 mg, 0.15 mmol). The reaction mixture was hydrogenated under 1 atm H2 for 3.5 hours, filtered, and concentrated in vacuo to yield methyl 3-amino-4-[(tert-butoxycarbonyl)amino]benzoate (0.40 g, 99%) as a white solid. ES-MS (M+H—C4H8)+=211.1.
