Versuchsvorschrift

To a stirred suspension of palladium on carbon (10%, 80 mg) in methanol (100 mL) was added a solution of (2S,4S)-benzyl 4-methoxy-2-(pyrazin-2-ylcarbamoyl)pyrrolidine-1-carboxylate 62A (400 mg, 1.12 mmol) in methanol (100 mL) under nitrogen. The suspension was hydrogenated with a hydrogen balloon atmosphere overnight. The resulting suspension was filtered through a pad of celite and washed with methanol. Concentration of the filtrate gave the product as an oil (250 mg, 100%) which was used without purification in the next step. LC/MS [M+H]+: 240; Ret time (Method F): 0.91 min.
