実験手順
To a solution of 9.00 g (S)-2-Cyclobutylcarbamoyl-pyrrolidine-1-carboxylic acid benzyl ester in 120 ml ethanol were added 1.0 g Pd/C (10%) and the suspension stirred under an atmosphere of hydrogen (3 bar) for 12 h. The reaction mixture was filtrated over a plug of Celite, washed with ethanol and concentrated to give the crude product which was used in the subsequent reaction. Yield: 3.3 g.
