Procedure
2.95 g of 4-benzyloxycarbonylaminobutyric acid N-(2-methoxyethyl)amide are hydrogenated in the presence of 0.24 g of 10% Pd/C in 150 ml of methanol and 100 ml of 0.1N hydrochloric acid for 2 hours at room temperature and under normal pressure. The reaction mixture is filtered and concentrated by evaporation. The crude title compound is obtained: 1H NMR (CD3OD), δ(ppm)=4.92(4H, s), 3.53-3.20 (4H, m), 3.34 (3H, 2.96 (2H, t, J=12 Hz), 2.37 (2H, t, J=12 Hz), 1.93 (2H, m).
