Reaktionsschritte

A solution of N-[2-(aminomethyl)-4-chloro-phenyl]-3-benzyl-triazol-4-amine 7b (439 mg, 1.40 mmol) in dry MeOH (18 mL) and EtOAc (18 mL) was treated with dibromozinc (126.0 mg, 0.56 mmol). The degassed mixture was then treated with 10% palladium on carbon (297.8 mg, 0.28 mmol) before affixing a hydrogen balloon. The mixture was stirred at room temperature for 2 h before filtering through celite and concentrating. The material was purified on an ISCO (0-100% MeOH in DCM) and the freebase was stirred in 4N HCl in dioxane for 30 min before evaporating to afford the title compound I-34 (mono hydrochloride salt) as a solid (291 mg, 80%). 1H NMR (500 MHz, DMSO-d6) δ 8.52 (1H, s) 8.47 (3H, m), 7.63 (1H, d), 7.53 (s, 1H), 7.48 (1H, d), 7.31 (1H, d) 4.12 (2H, q). MS m/z: 224.1 (M+H)+.
