Procedure

Under an atmosphere of nitrogen, Pd/C (10%, 1.36 g) was charged to a round bottom flask. Ethyl 2-(3-nitro-pyridin-2-yl)-acetate (8.6 g, 0.41 mol) was dissolved in ethanol (200 mL) and added to the reaction vessel. The reaction was placed under an atmosphere of hydrogen and stirred at room temperature for 30 min. The reaction was filtered through celite and the filtrate was concentrated in vacuo to afford the product as a tan solid (6.94 g, 94% yield).
