Carbamic acid, [(1S,3S)-3-aminocyclopentyl]-, 1,1-dimethylethyl ester (9CI) Chemical Properties, Uses, Production
Uses
tert-butyl N-[(1S,3S)-3-aminocyclopentyl]carbamate is used as a reactant in the synthesis of C-2 hydroxyethyl imidazopyrrolo pyridines as JAK1 inhibitors.
Synthesis

A flask containing tert-butyl [(1S,3S)-3-aminocyclopentyl]carbamate (16.5 g, crude ~0.05 mol) and 1.7 g Pd-C (10% paste) in MeOH (300 mL) was exposed to a positive pressure of hydrogen gas (balloon) over weekend. The catalyst was filtered off and the mixture was concentrated to afford the title compound (9.5 g) as a thick colorless viscous oil. Tert-butyl [(1S,3S)-3-aminocyclopentyl]carbamate, Yield (9.5 g)
