Reaction Steps

A mixture of (tert-butoxy)-N-[2-(4-nitrophenyl)ethyl]-carboxamide (570 mg, 2.15 mmol, Step A), iron powder (602 mg, 10.75 mmol) and NH4Cl (82 mg, 1.5 mmol) in EtOH (6 mL) and H2O (6 ml) was stirred for 4 h at 80° C. Filtration and concentration gave the crude compound, which was used in next step without further purification.
