Tert-butyl (1-(4-nitrophenyl)ethyl)carbamate → tert-butyl N-[1-(4-aminophenyl)ethyl]carbamate

Participants

Reaction Steps

A suspension of 10% Pd/C (1.25 g) and tert-butyl (1-(4-nitrophenyl)ethyl)carbamate (A130) (3.78 g, 14.2 mmol) in EtOAc (50 mL) was stirred under a hydrogen atmosphere for 3 hours. The resulting solution was filtered through a pad of Celite, washing with EtOAc, then the filtrate was concentrated in vacuo to give the title compound A131 as a viscous oil (3.01 g, 89%); 1H NMR (300 MHz, CDCl3) δ 7.11 (d, J=8.1 Hz, 2H), 6.70 (d, J=8.0 Hz, 2H), 4.70 (brs, 2H), 1.44 (m, 14H). LCMS-B: 4.444 min; m/z 237 [M+H]+.
