実験手順
A suspension of 10% Pd on carbon (9.21 g, 8.66 mmol) in a solution of the ethyl (6-nitropyridin-3-yl)acetate (36.4 g, 173 mmol) in EtOH (364 mL) was hydrogenated at 20 psi and 25° C. for 2 h. The suspension was filtered through Solka Floc eluting with 200 mL EtOH. The filtrate was concentrated and solvent switched with EtOAc, then concetrated to afford the title compound.
