Reaction Steps

A mixture of tert-butyl 2-(4-nitrophenyl)propanoate (14.4 g, 57.3 mmol) and 10% palladium on carbon (1.44 g, 10% by weight) in ethanol (150 mL) was shaken under an atmosphere of hydrogen at 40 psi for 2 h. After this time, the reaction was filtered through diatomaceous earth, and concentrated under reduced pressure to afford tert-butyl 2-(4-aminophenyl)propanoate (12.5 g, 99%) as an orange oil: 1H NNR (300 MHz, CDCl3) δ 7.07 (d, J=9.1 Hz, 2H), 6.63 (d, J=9.1 Hz, 2H), 3.60 (s, 2H), 3.49 (q, J=7.1 Hz, 1H), 1.40 (d, 3H), 1.38 (s, 9H); ESI MS m/z 222 [M+H]+.
