| Product | 1-[(R)-methoxycarbonylamino-cyciohexyl-acetyl]-pyrrolidine-2-(S)-carboxylic acid | HCID 22958491 | 89% |
Reaction Steps
1.17 g 1-[(R)-methoxycarbonylamino-cyclohexyl-acetyl]-pyrrolidine-2-(S)-carboxylic acid benzyl ester were dissolved in 90 mL of methanol and hydrogenated for 3 h at room temperature using 0.8 g palladium on charcoal (10%) as catalyst. Filtration followed by concentration in vacuo affords 0.80 g (89%) of the title compound as a colorless oil.
