実験手順
(The following reaction is done in an N2 atmosphere.) Dissolve N-(3-Nitro-phenyl)-3-(3,4,5-trimethoxy-phenyl)-propionamide (89) (100 mg, 0.28 mmol) in MeOH (4.5 mL) and add Pd on carbon (10% (w/w) Pd content, 29.5 mg, 0.028 mmol) followed by NH4CO2H (175 mg, 2.77 mmol) at rt. Degas the reaction mixture carefully (flush with N2) and stir it for 75 min at rt. Filtrate reaction mixture through a short pad of celite and remove solvent. Treat residue with EtOAc, filtrate again through a short pad of celite and remove solvent to obtain N-(3-Amino-phenyl)-3-(3,4,5-trimethoxy-phenyl)-propionamide (90) (91 mg, 99%) as a white solid. No further purification. 1H NMR (400 MHz, CD3OD): 2.65 (t, 2H, J=7.5 Hz); 2.98 (t, 2H, J=7.5 Hz); 3.75 (s, 3H); 3.82 (s, 6H); 6.50 (dd, 1H, J1=8.0 Hz, J2=2.0 Hz); 6.58 (s, 2H); 6.80 (dd, 1H, J=8.0 Hz, J2=2.0 Hz); 7.02-7.07 (m, 1H); 7.04 (t, 1H, J=8.0 Hz).
