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, (1R,3S)-3-(5-amino-pyridin-2-ylamino)-cyclopentanecarboxylic acid methyl ester was prepared by the hydrogenation of (1R,3S)-3-(5-nitro-pyridin-2-ylamino)-cyclopentanecarboxylic acid methyl ester. This material was directly used in the next step without further purification.
