Reaction Steps

1-(1-Cyclopentenyl)-4-nitro-benzene (225 mg, 1.19 mmol) in methanol (10 mL) and dichloromethane (2.5 mL) was treated with 10% Pd/C (70 mg) and stirred under H2 atmosphere for 1 h at room temperature. The reaction was filtered and concentrated in vacuo to provide 4-cyclopentylaniline (180 mg, 94% yield). 1H NMR (400.0 MHz, MeOD) δ 7.01 (d, J=8.2 Hz, 2H), 6.73-6.70 (m, 2H), 2.88 (dd, J=2.3, 17.3 Hz, 1H), 2.00-1.95 (m, 2H), 1.80-1.75 (m, 2H), 1.70-1.64 (m, 2H), 1.56-1.49 (m, 2H).
