Reaction Steps

The compound (16.5 g, 50 mmol) of example 41 was dissolved in methanol, added with 0.4 g 10% Pd/C, and hydrogenized at the normal temperature and pressure. When hydrogen was not absorbed by the reaction mixture any more, the reaction was quenched and Pd/C was filtered off. The filtrate was concentrated to a small volume, and fed with HCl gas to generate a white solid. The obtained solid was filtered and dried to give the hydrochlorate of the title compound (16.4 g. yield: 97%). 1H NMR 1H NMR (CDCl3) δ: 7.68 (1H, d), 7.43 (1H, dd), 7.24 (1H, d), 4.04 (2H, t), 2.57 (2H, q), 2.46 (2H, q), 1.75 (2H, m), 1.19 (3H, t), 1.04 (3H, t), 0.96 (3H, t).
