Procedure
With a method similar to that used for the preparation of (S)-3-(5-amino-pyridin-2-ylamino)-pyrrolidine-1-carboxylic acid tert-butyl ester above, (R)-1-(5-amino-pyridin-2-yl)-pyrrolidin-3-yl]-carbamic acid tert-butyl ester was prepared by the hydrogenation of (R)-1-(5-nitro-pyridin-2-yl)-pyrrolidin-3-yl]-carbamic acid tert-butyl ester. This material was directly used in the next step without further purification.
