실험 절차

A mixture of ethyl 3-(3-nitrophenyl)acrylate (63 g, 284 mmol) and Pd/C (6.3 g) in MeOH (800 ml) were stirred under 40 psi of H2 at room temperature for 2 hr, then filtered through celite to give the product ethyl 3-(3-aminophenyl)propanoate (48 g, yield 89%). 1H NMR MeOD 400 MHz. δ 7.00-6.51 (m, 4H), 4.10-4.04 (m, 2H), 2.79-2.76 (m, 2H), 2.56-2.52 (m, 2H), 1.20-1.17 (m, 3H).
