실험 절차

A mixture of (S)-3-(5-nitro-pyridin-2-ylamino)-pyrrolidine-1-carboxylic acid tert-butyl ester (500 mg, 1.67 mmol), 10% palladium on carbon (80 mg) in methanol (10 mL) was hydrogenated at 50 psi in a Parr Shaker at room temperature for 2 h. The reaction mixture was then filtered through a plug of celite and the filtration pad was washed with ethyl acetate. The organic layers were collected and concentrated to give (S)-3-(5-amino-pyridin-2-ylamino)-pyrrolidine-1-carboxylic acid tert-butyl ester (490 mg, crude) as a light red solid, which was directly used in the next step without further purification.
