反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of 2-[(N-carboxy-L-prolyl)amino]acetamide N-benzyl ester (Ex. 9, 610 mg, 2 mmoles) in glacial acetic acid (8 ml) containing hydrogen chloride (2 mmoles) is agitated with palladium on charcoal (5%, 50 mg) in an atmosphere of hydrogen in the same manner as described in Example 6 until one molar equivalent of hydrogen has been consumed. Filtration, evaporation of the filtrate and drying of the residue under reduced pressure gives the title compound which is used as such in the subsequent step. has been consumed Filtration, evaporation of the filtrate drying of the residue under reduced pressure
