Versuchsvorschrift

(S)-Benzyl 4-(3-(2-fluoro-5-methyl-4-(methylsulfonyl)phenylamino)-2-oxopyrrolidin-1-yl)piperidine-1-carboxylate (906 mg, 1.80 mmol) was dissolved in EtOH (15 mL) and 10% Pd/C was added and stirred under balloon pressure of hydrogen overnight. The reaction was filtered and concentrated to afford (S)-3-(2-fluoro-5-methyl-4-(methylsulfonyl)phenylamino)-1-(piperidin-4-yl)pyrrolidin-2-one (680 mg, 1.84 mmol, 102% yield).
