HCID 59402251, compound → (S)-Methyl-pyrrolidin-3-yl-carbamic acid tert-butyl ester

Participants

Reaction Steps

To a suspension of 5% Pd/C (4.60 g, 2.16 mmol) in ethanol (40 mL) was added slowly a solution of (S)-benzyl 3-(tert-butoxycarbonyl(methyl)amino)pyrrolidine-1-carboxylate (7.2 g, 21.6 mmol) in methanol (20 mL). The mixture was evacuated and backfilled with nitrogen and then evacuated and backfilled with hydrogen then stirred under a hydrogen atmosphere for 2 hours. The suspension was filtered through a pad of Celite and washed with methanol (60 mL). The filtrate was concentrated under reduced pressure to afford (S)-tert-butyl methyl(pyrrolidin-3-yl)carbamate (4.3 g, 99%).
