Additional EtOH (150 mL) was added followed by a solution of HCl in dioxane (4 M, 11.4 mL, 45.6 mmol). The mixture was hydrogenated on a Parr shaker at 45 psi for 20 h and the catalyst was removed by filtration through celite. The solution was concentrated to afford (3-aminomethyl-phenyl)-acetic acid ethyl ester as the hydrochloride salt (7.31 g). 1H NMR (400 MHz, CD3OD) δ7.42-7.32 (m, 4H), 4.12 (q, 2H), 4.09 (s, 2H), 3.68 (s, 2H), 1.23 (t, 3H).
