実験手順
To a solution of ethyl (2-amino-6-(2-methoxyethoxy)-3-nitropyridin-4-yl)(4-((diethoxyphosphoryl)methyl)benzyl)carbamate (1 equiv.) in EtOH (0.05 M) was added 10% Pd/C (50% equiv. by weight) in a Paar Shaker Flask. The reaction mixture was placed in a Paar Shaker at 55 psi for 4 h. At this point the reaction mixture was passed through a pad of Celite, washing with a 2:1 mixture of CHCl3:MeOH. The combined organic layers were dried over anhydrous Na2SO4 and the volatiles were removed in vacuo. The resulting residue was used in the next step without further purification.
