실험 절차

(2S)-2-tert-Butoxycarbonylamino-3-(2-aminophenyl-amino)-propionic acid. A mixture of (2S)-2-tert-Butoxycarbonylamino-3-(2-nitrophenylamino)propionic acid (12.65 g, 40.5 mmol) and 0.5 g of 10% Pd/C in 100 ml of MeOH under hydrogen at 1 atmosphere was stirred for 4 h. The solution was filtered through Celite 545 and the filtrate evaporated in vacuo to afford the 11.95 g of the title compound in quantitative yield as a dark brown solid that was used without purification: 1H NMR (CD3OD) δ 6.75-6.70 (3H,m), 6.65-6.58 (1H, m), 4.35-4.3 1H, m), 3.6-3.38 (2H, m), 1.45 (9H, s).
