Reaktionsschritte

A mixture containing 2-cyanomethylbenzimidazole (2.0 g, 12.7 mmol), 10% Pd/C (1.0 g), and AcOH (40 mL) was hydrogenated at 42 psi for 6 h in a Parr apparatus. The reaction mixture was filtered through a bed of Celite® and concentrated to give the title compound (3.4 g, 95%): 1H NMR (250 MHz, CDCl3) δ 7.04-28.13 (m, 7H), 3.17-3.39 (m, 4H); MS (ES) m/e 162.0 (M+H)+.
