Procedure

A solution of N-(5-nitropyridin-2-yl)-2-phenylacetamide (4.35 g, 16.9 mmol) in EtOH (75 mL) and EtOAc (75 mL) is stirred at rt and ammonium formate (4.27 g) and 10% Pd/C (500 mg) are added. The mixture is heated at reflux for 30 min, cooled, filtered through celite and evaporated to afford the title compound as an off-white solid which was used without further purification.
