tert-Butyl carbamate → tert-Butyl [(3S)-1-(5-aminopyridin-2-yl)pyrrolidin-3-yl]carbamate

Participants

Reaction Steps

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, (S)-1-(5-amino-pyridin-2-yl)-pyrrolidin-3-yl]-carbamic acid tert-butyl ester was prepared by the hydrogenation of (S)-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.
