실험 절차

0.13 g of 20% w/w palladium-on-carbon was added to a solution of 0.99 g (0.0025 mole) of 1-t-butoxycarbonyl-3-dibenzylamino-4-methoxypyrrolidine dissolved in 15 ml of ethanol, and the mixture was stirred vigorously at 50° C. for 4 hours in an atmosphere of hydrogen. The catalyst was filtered off from the reaction mixture, after which the filtrate was concentrated by evaporation under reduced pressure, to give 0.44 g of 3-amino-1-t-butoxycarbonyl-4-methoxypyrrolidine as a colorless oil.
