실험 절차

To a mixed solution of diethyl α-hydroxy-4-nitrobenzylphosphonate (1.42 g) and methanol (30 mL) was added 10% palladium-carbon (0.14 g) and the mixture was stirred at room temperature under an atmospheric hydrogen pressure for 3 hrs. Palladium-carbon was removed from the reaction mixture by filtration and the filtrate was concentrated to give diethyl 4-amino-α-hydroxybenzylphosphonate as a solid (1.02 g, yield 80%).
